Description

Technical Field

[0001] This application relates to the technical field of oral irrigators, and in particular to an oral irrigator with a self-cleaning water storage container. Background Art

[0002] An oral irrigator is an auxiliary tool for oral cleaning. It is a tool that uses the impact of pulsed water flow to clean teeth and dental floss. Its main structure includes an installation housing, a water storage tank installed at the bottom of the installation housing, a pumping mechanism installed inside the installation housing and connected to the water storage tank, and a nozzle installed at the upper end of the installation housing and connected to the pumping mechanism. When a user needs to use the oral irrigator, they only need to start the pumping mechanism to draw the water source inside the water storage tank and spray it out through the nozzle. Then, the user picks up the oral irrigator and aligns the nozzle with their teeth to achieve the effect of cleaning teeth.

[0003] However, since the user needs to insert the nozzle into the mouth every time they use the oral irrigator, some of the dirt flushed by the oral irrigator will stick to the nozzle. Therefore, the user needs to clean the nozzle every time after using the oral irrigator. For this reason, this application proposes an oral irrigator with a self-cleaning water storage container to make it more convenient for the user to clean the nozzle. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of this application is to provide an oral irrigator with a self-cleaning water storage container to make it more convenient for the user to clean the nozzle.

[0005] The above object of this application is achieved through the following technical solutions: An oral irrigator with a self-cleaning water storage container includes an installation housing, a water storage tank installed at the bottom of the installation housing, a pumping mechanism installed inside the installation housing and connected to the water storage tank, and a nozzle installed at the upper end of the installation housing and connected to the pumping mechanism. A through hole that penetrates the installation housing and is connected to the water storage tank is opened at the upper end of the installation housing. A waterproof fan is installed inside the water storage tank, and the blowing surface of the waterproof fan faces upward.

[0006] By adopting the above technical solutions, when the user needs to clean the nozzle, they only need to drop the nozzle into the water storage tank through the through hole, and then start the waterproof fan. The waterproof fan stirs the water in the water storage tank, causing the water in the water storage tank to drive the nozzle to rotate, thereby completing the cleaning of the nozzle. After the cleaning is completed, the installation housing is simply inverted to drain the water in the water storage tank and let the nozzle fall out of the water storage tank. In this way, the user does not need to clean the nozzle themselves, making it more convenient for the user to clean the nozzle. Moreover, due to the setting of the through hole, when the user adds water to the water storage tank, they can also add water to the water storage tank through the through hole, making it more convenient for the user to replenish the water source in the water storage tank. Additionally, due to the setting of the waterproof fan, the water storage tank can dry faster, preventing scale from forming in the water storage tank and making the water storage tank cleaner.

[0007] Further, a protective cover covering the waterproof fan is fixedly arranged inside the water storage tank, and ventilation openings penetrating the protective cover are formed on the upper surface and the periphery of the protective cover.

[0008] By adopting the above technical solution, although the setting of the waterproof fan makes it more convenient for users to clean the nozzle, during the operation of the waterproof fan, its fan blades may hit the nozzle, resulting in damage to the nozzle or the nozzle jamming the waterproof fan and causing the waterproof fan to fail to work properly. The setting of the protective cover solves this technical problem. Through the setting of the protective cover and the ventilation openings, while the protective cover separates the nozzle from the waterproof fan, the waterproof fan can normally stir the water source and rotate, improving the stability during the use of the waterproof fan.

[0009] Further, ventilation structures for quickly drying the water storage tank are arranged on both sides of the water storage tank.

[0010] Further, the ventilation structure includes ventilation openings formed on opposite sides of the water storage tank and penetrating the water storage tank, a rotating shaft located in the middle of the ventilation openings and rotatably connected to the water storage tank, and a blocking plate fixedly arranged on the rotating shaft for blocking the ventilation openings. The bottom end of the rotating shaft passes through the water storage tank and extends out from the bottom surface of the water storage tank.

[0011] By adopting the above technical solution, although the waterproof fan can make the water storage tank dry faster, since the air flow blown out by the waterproof fan can only flow out from the through hole, it causes the user to need to keep the waterproof fan on for a long time to completely dry the water storage tank, which is very energy - wasting. The setting of the ventilation structure solves this technical problem. Through the setting of the ventilation structure, when the user does not use the oral irrigator, the blocking plates on both sides of the water storage tank can be rotated so that the two blocking plates no longer block the ventilation openings and are in a collinear state, enabling the air flow blown out by the waterproof fan to flow out through the ventilation openings and the through hole, making the gas inside the water storage tank exchange more frequently with the external gas, thereby quickly drying the water storage tank, improving the efficiency of the waterproof fan in drying the water storage tank, saving the energy consumption of the waterproof fan in completely drying the water storage tank, and when the user wants to further save energy consumption, the waterproof fan can be turned off, and only by opening the ventilation openings, the external gas can flow into the inside of the water storage tank, and waiting for a longer time to dry the water storage tank.

[0012] Further, first sealing structures and second sealing structures for improving the sealing performance of the water storage tank are arranged on the end faces of both ends of the blocking plate and on both sides inside the ventilation openings.

[0013] Further, the first sealing structure includes a sealing strip fixedly arranged on one end face of the plugging plate along the height direction of the plugging plate, a connecting plate arranged on one side inside the ventilation opening and at the same height as the sealing strip, a plugging strip arranged on one side of the sealing strip at the same height and extending rightward, and a plugging groove opened on the connecting plate with an opening facing outside the water storage tank and at the same height as the sealing strip. The connecting plate is fixedly connected to the water storage tank. The second sealing structure has the same structure as the first sealing structure, but the arrangement directions of the plugging strip and the plugging groove in the second sealing structure are opposite to those in the first sealing structure. The second sealing structure is arranged on the other end face of the plugging plate and the other side inside the ventilation opening.

[0014] By adopting the above technical solution, although the setting of the ventilation structure improves the efficiency of the waterproof fan in drying the water storage tank, due to the rotatable setting of the plugging plate, there are small gaps left between the plugging plate and the inner side wall of the ventilation opening, which reduces the sealing performance of the water storage tank. The setting of the first sealing structure and the second sealing structure solves this technical problem. When the user rotates the plugging plate to block the ventilation opening, the sealing strip and the connecting plate are in contact. At this time, the plugging strip is inserted into the plugging groove, resulting in a concave-convex fit between the sealing strip and the connecting plate, thus improving the sealing performance of the water storage tank and effectively preventing the water storage tank from leaking. The arrangement directions of the plugging strip and the plugging groove in the second sealing structure are opposite to those in the first sealing structure to enable the normal rotation of the plugging plate.

[0015] Further, the bottom surface inside the ventilation opening is provided with a third sealing structure on both sides of the rotating shaft for improving the sealing performance of the water storage tank.

[0016] Further, the third sealing structure includes two receiving grooves opened on the bottom surface inside the ventilation opening and located on both sides of the rotating shaft respectively, an extrusion rubber plugged in the receiving grooves, and a support spring arranged in the receiving grooves for pushing the extrusion rubber to extend out of the receiving grooves.

[0017] By adopting the above technical solution, although the setting of the ventilation structure improves the efficiency of the waterproof fan in drying the water storage tank, due to the rotatable setting of the plugging plate, each rotation of the plugging plate will rub the bottom surface inside the ventilation opening, resulting in a gap between the bottom surface of the plugging plate and the bottom surface inside the ventilation opening after using the plugging plate for a period of time, reducing the sealing performance of the water storage tank. The setting of the third sealing structure solves this technical problem. Through the setting of the third sealing structure, when the plugging plate blocks the ventilation opening, the bottom surface of the plugging plate will compress the extrusion rubber, causing the extrusion rubber to move downward and compress the support spring. At the same time, the support spring pushes the extrusion rubber to press against the bottom surface of the plugging plate, thus preventing a gap from appearing between the bottom surface of the plugging plate and the bottom surface inside the ventilation opening, thereby improving the sealing performance of the water storage tank.

[0018] Furthermore, a suction cup is fixedly provided at the bottom end of the rotating shaft, and the adsorption surface of the suction cup faces downward.

[0019] By adopting the above technical solution, although the ventilation structure improves the efficiency of the waterproof fan in drying the water storage tank, the rotating shaft extending from the bottom surface of the water storage tank will cause the entire oral irrigator to be unstable. If the rotating shaft is not set to extend from the bottom surface of the water storage tank, it will be very inconvenient for the user to rotate the plugging plate. The setting of the suction cup solves this technical problem. When the user rotates the plugging plate to open the ventilation opening, the user only needs to place the oral irrigator on the table so that the suction cup adsorbs the table. In this way, it can not only make the placement of the oral irrigator more stable for the user, but also rotate the plugging plate through the rotating shaft. At the same time, after the suction cup adsorbs the table, it can also prevent the plugging plate from rotating, so that the plugging plate will not rotate to block the ventilation opening due to the flow of air, improving the stability during ventilation of the ventilation structure.

[0020] Furthermore, a water leakage port penetrating the water storage tank is opened on the bottom surface of the water storage tank, and a water leakage plug for plugging the water leakage port is provided on the bottom surface of the water storage tank.

[0021] By adopting the above technical solution, when the user needs to drain the water in the water storage tank, the user only needs to pull out the water leakage plug, making it more convenient for the user to drain the water in the water storage tank.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: Through the setting of the through hole and the waterproof fan, when the user needs to clean the nozzle, the user only needs to throw the nozzle into the water storage tank through the through hole, and then start the waterproof fan. The waterproof fan stirs the water in the water storage tank so that the water in the water storage tank drives the nozzle to rotate, thereby completing the cleaning of the nozzle. After the cleaning is completed, the installation shell is only needed to be inverted so that the water in the water storage tank is drained and the nozzle falls out of the water storage tank. In this way, the user does not need to clean the nozzle by himself, making it more convenient for the user to clean the nozzle. And through the setting of the through hole, when the user adds water to the water storage tank, the user can also add water to the water storage tank through the through hole, making it more convenient for the user to replenish the water source in the water storage tank. And through the setting of the waterproof fan, the water storage tank can also be dried faster, preventing scale from appearing in the water storage tank and making the water storage tank cleaner.

Detailed implementation manners

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Example, referring to Figure 1 , Figure 2 , a dental irrigator for self-cleaning water storage container, comprising a mounting housing 1, a water storage tank 10 mounted at the bottom end of the mounting housing 1, a pumping mechanism mounted inside the mounting housing 1 and communicating with the water storage tank 10, and a nozzle 11 mounted at the upper end of the mounting housing 1 and communicating with the pumping mechanism. A through hole 12 is further opened at the upper end of the mounting housing 1. This through hole 12 not only penetrates the entire mounting housing 1, but also communicates with the inside of the water storage tank 10. Such a design not only provides great convenience for users, but also endows the dental irrigator with more functions.

[0027] Inside the water storage tank 10, a waterproof fan 13 is installed. The blowing surface of this waterproof fan 13 faces upward and is specifically designed to stir the water in the water storage tank 10. When the user needs to clean the nozzle 11, simply put the nozzle 11 into the water storage tank 10 through the through hole 12, and then start the waterproof fan 13. The rotation of the fan will drive the water in the water storage tank 10 to form a vortex, and then make the nozzle 11 rotate in the water, thereby realizing a comprehensive cleaning of the nozzle 11. This design not only saves the trouble of the user manually cleaning the nozzle 11, but also greatly improves the cleaning efficiency and effect.

[0028] After the cleaning is completed, the user only needs to invert the mounting housing 1, and can easily drain the water in the water storage tank 10, and make the nozzle 11 fall out of the water storage tank 10 naturally. Such an operation is simple and convenient, greatly improving the user experience.

[0029] In addition, the setting of the through hole 12 also provides great convenience for the user to supplement the water source in the water storage tank 10. The user does not need to open any complex lids or disassemble parts, and can directly add water to the water storage tank 10 through the through hole 12. This design not only simplifies the operation process, but also improves the water filling speed and efficiency.

[0030] The addition of the waterproof fan 13 further enhances the practicality and durability of the oral irrigator. When the oral irrigator is not in use, the waterproof fan 13 can be activated to dry the water storage tank 10. The strong wind of the fan can quickly remove the moisture in the water storage tank 10, preventing the formation of water scale and the growth of bacteria. In this way, the water storage tank 10 can always maintain a dry and clean state, providing a healthier and safer water - using environment for users.

[0031] Although the setting of the waterproof fan 13 greatly facilitates the cleaning process of the nozzle 11, in actual operation, engineers have also noticed a potential technical challenge: when the waterproof fan 13 rotates at high speed, its fan blades may accidentally collide with the nozzle 11. Such a collision may not only damage the nozzle 11, affecting its normal water - spraying function, but also cause the nozzle 11 to get stuck between the fan blades, thus hindering the normal operation of the waterproof fan 13 and even causing equipment failure.

[0032] To effectively solve this technical problem, in this embodiment, a protective cover 14 is provided and fixedly installed inside the water storage tank 10. The protective cover 14 wraps the waterproof fan 13, forming an effective safety barrier. This design not only ensures that the nozzle 11 does not directly contact the fan blades during the cleaning process, thus avoiding potential collision damage and jamming risks, but also guarantees that the waterproof fan 13 can work continuously and stably without interference.

[0033] Moreover, ventilation openings penetrating the entire protective structure are provided on the upper surface and the periphery of the protective cover 14. The setting of these ventilation openings not only ensures that the waterproof fan 13 can obtain sufficient air circulation during operation to maintain its normal agitation of the water source and generation of rotational power, but also ensures that excessive air - flow resistance does not form inside the protective cover 14, thus affecting the working efficiency of the fan.

[0034] In summary, through the setting of the protective cover 14 and the ventilation openings thereon, this embodiment not only successfully solves the possible collision problem between the waterproof fan 13 and the nozzle 11, but also further improves the stability and reliability of the waterproof fan 13 during use.

[0035] Although the setting of the waterproof fan 13 significantly accelerates the drying process of the water storage tank 10, however, the air flow blown out can only be discharged through a single through - hole 12. This limitation causes users to have to run the waterproof fan 13 for a long time to ensure that the inside of the water storage tank 10 is completely dry. This approach is not only inefficient but also greatly wastes energy. To solve this technical problem, in this embodiment, ventilation structures 2 for promoting rapid drying are added on opposite sides of the water storage tank 10.

[0036] This ventilation structure 2 is composed of multiple key components: Firstly, on both sides of the water storage tank 10, ventilation openings 20 that penetrate the entire box body are opened in this embodiment. These ventilation openings 20 provide a direct channel for the exchange of internal and external gases. Secondly, a rotating shaft 21 is equipped in the middle of each ventilation opening 20, and these rotating shafts 21 are rotatably connected to the water storage tank 10. Finally, a blocking plate 22 is fixedly installed on each rotating shaft 21 for closing the ventilation opening 20 when needed.

[0037] Moreover, the bottom end of the rotating shaft 21 penetrates the bottom surface of the water storage tank 10 and extends outwards. This design enables users to rotate the blocking plate 22 without touching it. Through this setting, when the oral irrigator is in a non-use state, users can conveniently rotate the blocking plates 22 on both sides of the water storage tank 10 so that they rotate from the original position of closing the ventilation openings 20 to a collinear state. In this state, the two blocking plates 22 no longer obstruct the flow of air, and the air flow blown by the waterproof fan 13 can smoothly flow out through the ventilation openings 20 and the original through holes 12, greatly enhancing the gas exchange efficiency between the inside and outside of the water storage tank 10.

[0038] This setting not only significantly improves the efficiency of the waterproof fan 13 when drying the water storage tank 10, but also effectively reduces the energy consumption required to reach the dry state by optimizing the air flow path. Furthermore, when users hope to further save energy, they can even choose not to start the waterproof fan 13. By simply opening the ventilation openings 20 and relying on the action of natural wind and time, the water storage tank 10 can also be dried. This flexible choice not only reflects the intelligence of the design but also fully meets the dual requirements of users for energy conservation and high efficiency.

[0039] Although the ingenious design of the ventilation structure 2 significantly improves the efficiency of the waterproof fan 13 when drying the water storage tank 10, however, due to the rotational connection characteristics of the blocking plate 22, there will inevitably be a certain small gap between it and the inner side wall of the ventilation opening 20. This gap not only reduces the overall sealing performance of the water storage tank 10 but also may cause potential water leakage problems, thereby affecting the use effect and user experience of the oral irrigator. To solve this technical problem, referring to Figure 3 In this embodiment, a first sealing structure 3 and a second sealing structure are provided at the contact part between the blocking plate 22 and the ventilation opening 20 to significantly improve the sealing performance of the water storage tank 10.

[0040] Specifically, the first sealing structure 3 is cleverly arranged on the end face of one end of the blocking plate 22 and on the corresponding side of the inside of the ventilation opening 20. The first sealing structure 3 is composed of multiple key components: first, it includes a blocking strip 30 fixedly arranged on the end face of one end of the blocking plate 22, and the blocking strip 30 extends along the height direction of the blocking plate 22. Secondly, it also includes a connecting plate 31 fixedly arranged on one side of the inside of the ventilation opening 20. The height of the connecting plate 31 matches the blocking strip 30, ensuring the tightness of the two when in contact. In order to further enhance the sealing effect, the present embodiment is fixedly provided with a plug-in strip 32 on one side of the blocking strip 30. The plug-in strip 32 has the same height as the blocking strip 30 and extends to the right, forming a unique plug-in structure. At the same time, a plug-in slot 33 is also provided on the connecting plate 31. The plug-in slot 33 opens toward the outside of the water tank 10, and the height also matches the blocking strip 30, providing a perfect space for the insertion of the plug-in strip 32.

[0041] In response to the first sealing structure 3, the second sealing structure is arranged on the other end face of the blocking plate 22 and the other side of the corresponding ventilation opening 20. Its structure is the same as the first sealing structure 3, but the arrangement directions of the plug strip 32 and the plug slot 33 are opposite. This arrangement solves the obstruction problem that the blocking plate 22 may encounter during the rotation process, ensuring that the blocking plate 22 can rotate smoothly and accurately close the ventilation opening 20.

[0042] When the user needs to rotate the blocking plate 22 to close the ventilation opening 20, the blocking strip 30 will abut against the connecting plate 31, and the plug-in strip 32 will be accurately inserted into the plug-in slot 33. In this process, a unique concave-convex matching structure is formed between the blocking strip 30 and the connecting plate 31, which greatly improves the sealing performance of the water tank 10 and effectively prevents water leakage. The opposite design of the plug-in strip 32 and the plug-in slot 33 in the second sealing structure ensures that the blocking plate 22 will not be hindered during the rotation process, thereby achieving the dual effects of both sealing and flexibility.

[0043] In summary, through the provision of the first sealing structure 3 and the second sealing structure, this embodiment not only successfully solves the sealing problem caused by the gap between the blocking plate 22 and the ventilation opening 20, but also further improves the overall performance and user experience of the oral irrigator.

[0044] Although the setting of the ventilation structure 2 improves the efficiency of the waterproof fan 13 in drying the water storage tank 10, due to the rotation setting of the blocking plate 22, each rotation of the blocking plate 22 will rub the bottom surface of the inside of the ventilation opening 20, resulting in a gap between the bottom surface of the blocking plate 22 and the bottom surface of the inside of the ventilation opening 20 after using the blocking plate 22 for a period of time, thereby reducing the sealing performance of the water storage tank 10. In order to solve this technical problem, referring to Figure 4In this embodiment, a third sealing structure 4 for enhancing the sealing performance of the water storage tank 10 is provided on the bottom surface inside the ventilation opening 20 and on both sides of the rotating shaft 21. The third sealing structure 4 includes two receiving grooves 40 opened on the bottom surface inside the ventilation opening 20 and located on both sides of the rotating shaft 21 respectively, an extrusion rubber 41 inserted into the receiving groove 40, and a support spring 42 arranged in the receiving groove 40 for pushing the extrusion rubber 41 to extend out of the receiving groove 40. By providing the third sealing structure 4, when the blocking plate 22 blocks the ventilation opening 20, the bottom surface of the blocking plate 22 will compress the extrusion rubber 41, causing the extrusion rubber 41 to move downward and compress the support spring 42. At the same time, the support spring 42 pushes the extrusion rubber 41 to press against the bottom surface of the blocking plate 22, thus preventing a gap from appearing between the bottom surface of the blocking plate 22 and the bottom surface inside the ventilation opening 20, thereby enhancing the sealing performance of the water storage tank 10.

[0045] Although the provision of the ventilation structure 2 improves the efficiency of the waterproof fan 13 in drying the water storage tank 10, the rotating shaft 21 extending from the bottom surface of the water storage tank 10 will cause the entire oral irrigator to be unstable. If the rotating shaft 21 is set not to extend from the bottom surface of the water storage tank 10, it will cause great inconvenience for the user to rotate the blocking plate 22. To solve this technical problem, in this embodiment, a suction cup 23 is fixedly provided at the bottom end of the rotating shaft 21, with the adsorption surface of the suction cup 23 facing downward. After the user rotates the blocking plate 22 to open the ventilation opening 20, the oral irrigator can be simply placed on the tabletop, enabling the suction cup 23 to adsorb the tabletop. In this way, the user can place the oral irrigator more stably, and can also rotate the blocking plate 22 through the rotating shaft 21. At the same time, after the suction cup 23 adsorbs the tabletop, it can also prevent the blocking plate 22 from rotating, so that the blocking plate 22 will not rotate and block the ventilation opening 20 due to the flow of air, enhancing the stability of the ventilation structure 2 during ventilation.

[0046] In this embodiment, a water leakage port 15 penetrating the water storage tank 10 is opened on the bottom surface of the water storage tank 10, and a water leakage plug 16 for plugging the water leakage port 15 is provided on the bottom surface of the water storage tank 10, so that when the user needs to drain the water in the water storage tank 10, the user only needs to pull out the water leakage plug 16, making it more convenient for the user to drain the water in the water storage tank 10.

[0047] Specific implementation process: When the user needs to clean the nozzle 11, the user only needs to throw the nozzle 11 into the water storage tank 10 through the through hole 12, and then start the waterproof fan 13. The waterproof fan 13 stirs the water in the water storage tank 10, causing the water in the water storage tank 10 to drive the nozzle 11 to rotate, thereby completing the cleaning of the nozzle 11. Then, the water leakage plug 16 is pulled out, and the two blocking plates 22 are rotated so as not to block the ventilation opening 20. Then, the cleaned nozzle 11 is taken out of the water storage tank 10 through the ventilation opening 20. At this time, the entire oral irrigator can be simply placed on the tabletop, enabling the suction cup 23 to adsorb the tabletop, so that the inside of the water storage tank 10 can be quickly dried.

[0048] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
