Description

Technical Field

[0001] This invention relates to the field of oral irrigator technology, specifically to an oral irrigator, a method for cleaning the water tank of the oral irrigator, a method for controlling the cleaning of teeth using the oral irrigator, and a method for controlling the rinsing of the oral irrigator. Background Technology

[0002] As living standards continue to improve, people are paying more attention to dental health. More and more users are using water flossers to remove plaque and keep their teeth fresh, and also using mouthwash to suppress odor and kill bacteria. However, if the water tank of a water flosser is not cleaned properly during use, it can easily become moldy or even breed bacteria that affect dental health. Because most water tanks are designed to be deep with small openings, it is very difficult for users to thoroughly clean the tank.

[0003] To better clean the water tank of a water flosser, one existing water flosser uses its own nozzle to clean the water tank, thereby increasing the cleaning power. However, in this solution, the water in the tank that needs to be cleaned is recycled, which results in a relatively low cleaning effect. In addition, the nozzle is located at the water tank opening, and the adjustable angle is small, which cannot meet the requirement of cleaning the water tank from all angles.

[0004] Therefore, a more optimized water flosser structure needs to be considered. Summary of the Invention

[0005] The first objective of this invention is to provide a water flosser that facilitates cleaning of the water tank.

[0006] A second objective of this invention is to provide a method for cleaning the water tank of a dental flosser that can improve the cleaning effect of the water tank.

[0007] A third objective of this invention is to provide a method for controlling the cleaning of a water flosser that can improve the cleaning effect on teeth.

[0008] The fourth objective of this invention is to provide a mouthwash control method for a water flosser that can improve mouthwash comfort.

[0009] To achieve the aforementioned first objective, the oral irrigator provided by the present invention includes a main body, a nozzle, a water circuit control component, and a first liquid tank; the oral irrigator also includes a second liquid tank, the first liquid tank being detachably mounted on the main body, the nozzle, the water circuit control component, and the second liquid tank being both mounted on the main body, the water circuit control component including a water pump, a first inlet pipe, a second inlet pipe, and a control valve, the inlet end of the first inlet pipe being inserted into the first liquid tank, the inlet end of the second inlet pipe being connected to the second liquid tank, the outlet ends of the first and second inlet pipes being connected to the inlet end of the water pump via the control valve, the control valve controlling the opening degree of the first and second inlet pipes, and the outlet end of the water pump being connected to the nozzle.

[0010] As can be seen from the above solution, the oral irrigator of the present invention, by setting up a first liquid tank and a second liquid tank, allows the first liquid tank to be detachably installed on the main body. When cleaning is required, the first liquid tank can be removed, and the second liquid tank can be used to provide cleaning water to clean the first liquid tank, ensuring the cleanliness of the cleaning water. Furthermore, the detachable nature of the first liquid tank facilitates the insertion of the nozzle into the first liquid tank for comprehensive cleaning, thereby improving the cleaning effect of the tank. In addition, the two water tanks facilitate the multi-functional application of the oral irrigator.

[0011] In a further design, a dirt level detector is installed at the nozzle outlet to detect the degree of dirt on the object's surface.

[0012] Therefore, by setting up a dirt level detector, it is easy to know the dirt level on the surface of the object to be cleaned.

[0013] In a further proposed solution, the level of dirt is detected by a color detector.

[0014] Therefore, by setting up a color detector, it is easy to detect the object being cleaned during cleaning, to know the degree of dirt by color, and to carry out corresponding cleaning control.

[0015] To achieve the second objective mentioned above, the water tank cleaning method for a water flosser provided by the present invention includes: controlling the water flosser to enter a preset water tank cleaning mode, controlling the valve to close the first water inlet pipe and open the second water inlet pipe, the water pump drawing cleaning liquid from the second liquid tank and spraying it out as a high-pressure liquid column through the nozzle; and controlling the nozzle to perform a cleaning operation on the first liquid tank that has been removed from the main body.

[0016] As can be seen from the above scheme, the water tank cleaning method of the oral irrigator of the present invention involves removing the first liquid tank from the main body and injecting cleaning liquid into the second liquid tank, closing the first water inlet pipe and opening the second water inlet pipe with the control valve, pumping the cleaning liquid from the second liquid tank and spraying it out as a high-pressure liquid column through the nozzle, and using the second liquid tank to provide cleaning water to clean the first liquid tank, which can ensure the cleanliness of the cleaning water. At the same time, the detachable first liquid tank makes it easy for the nozzle to be inserted into the first liquid tank for all-round cleaning, thereby improving the cleaning effect of the water tank.

[0017] In a further embodiment, when controlling the nozzle to clean the first liquid tank, the method also includes: using a dirt level detector to detect the degree of dirt on the inner wall of the first liquid tank; and controlling the water pressure of the nozzle according to the degree of dirt.

[0018] Therefore, it can be seen that by using a dirt level detector to detect the dirt level on the inner wall of the first liquid tank, and using the dirt level to control the water pressure of the nozzle, the rationality of the water pressure can be improved, thus enhancing the cleaning effect.

[0019] In a further embodiment, the step of detecting the degree of dirt on the inner wall of the first liquid tank using a dirt level detector includes: acquiring color information of the inner wall of the first liquid tank using a color detector; and matching the color information acquired by the color detector with preset color information to confirm the degree of dirt.

[0020] Therefore, matching the color information obtained by the color detector with the preset color information can improve the accuracy of the degree of dirtiness.

[0021] To achieve the aforementioned third objective, the oral irrigator cleaning control method provided by the present invention includes: when a tooth spraying command is received, a control valve closes the first water inlet pipe and opens the second water inlet pipe, controlling the nozzle to spray out plaque revealing agent for spraying teeth; when a cleaning command is received, a color detector is used to detect the color of the tooth revealing agent, and the water pressure of the nozzle is determined based on the color of the revealing agent; the control valve opens the first water inlet pipe and closes the second water inlet pipe, and the water pump is controlled to draw clean water from the first liquid tank for tooth rinsing based on the water pressure.

[0022] As can be seen from the above scheme, the teeth cleaning control method of the oral irrigator of the present invention injects plaque revealing agent into the second liquid tank. When a teeth spraying command is obtained, the nozzle is first controlled to spray plaque revealing agent on the teeth. Then, when a teeth cleaning command is obtained, a color detector is used to detect the color of the revealing agent on the teeth. The water pressure of the nozzle is determined according to the color of the revealing agent, thereby improving the rationality of the water pressure and improving the teeth cleaning effect.

[0023] In a further proposed approach, the step of using a color detector to detect the color of the indicator on the teeth includes: performing an indicator color level test on all teeth, and using the color corresponding to the tooth with the highest indicator color level as the indicator color.

[0024] Therefore, using the color corresponding to the tooth with the highest display color grade as the display color can improve the rationality of the water pressure output.

[0025] To achieve the fourth objective mentioned above, the mouthwash control method for the oral irrigator provided by the present invention includes: when a command to enter the mouthwash mode is received, controlling the opening degree of the first water inlet pipe and the second water inlet pipe according to a preset mixing ratio of clean water and mouthwash; and controlling the nozzle to spray mouthwash to perform the mouthwash operation.

[0026] As can be seen from the above scheme, the mouthwash control method of the oral irrigator of the present invention injects clean water into the first liquid tank, injects mouthwash into the second liquid tank, and controls the opening of the first water inlet pipe and the second water inlet pipe according to the preset mixing ratio of clean water and mouthwash. This makes it easy to control the mixing degree of clean water and mouthwash, avoids mouthwash irritating the oral cavity, and improves mouthwash comfort.

[0027] In a further embodiment, after receiving the command to enter the gargling mode, the method also includes: obtaining the number of times the gargling mode is used within a preset time period; and sending a prompt message when the number of gargling exceeds the preset number.

[0028] Therefore, by obtaining the number of times mouthwash is used within a preset time period and sending a reminder message when the number of mouthwashes exceeds the preset number, it is possible to avoid excessive use of mouthwash, which can irritate the oral cavity, harm beneficial oral microorganisms, disrupt the balance of bacteria in the oral cavity, and thus cause oral diseases.

[0029] In a further embodiment, when controlling the nozzle to spray mouthwash for rinsing, the method also includes: determining whether a ratio adjustment command for adjusting the preset mixing ratio has been obtained; if so, adjusting the opening of the first water inlet pipe and the second water inlet pipe according to the ratio adjustment command.

[0030] Therefore, when controlling the nozzle to spray mouthwash for rinsing, the preset mixing ratio can be adjusted to meet the user's habits and improve the user experience. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0039] Water flosser example:

[0040] like Figure 1 and Figure 2As shown, in this embodiment, the oral irrigator includes a main body 1, a nozzle 2, a water control assembly 3, a first liquid tank 4, and a second liquid tank 5. The first liquid tank 4 is detachably mounted on the main body 1. The nozzle 2, the water control assembly 3, and the second liquid tank 5 are all disposed on the main body 1. The nozzle 2 is located at the top of the main body 1. The second liquid tank 5 is located within a receiving cavity (not shown) of the main body 1, and the second liquid tank 5 is integrally formed with the main body 1. Of course, although the second liquid tank 5 is not shown in the figure as having an opening, those skilled in the art should know that the second liquid tank 5 has an opening for operations such as liquid injection, liquid drainage, or cleaning.

[0041] The water circuit control component 3 includes a water pump 31, a first inlet pipe 32, a second inlet pipe 33, and a control valve 34. The inlet end of the first inlet pipe 32 is inserted into the first liquid tank 4, and the inlet end of the second inlet pipe 33 is connected to the second liquid tank 5. The outlet ends of both the first and second inlet pipes 32 and 33 are connected to the inlet end of the water pump 31 via the control valve 34. The control valve 34 controls the opening degree of the first and second inlet pipes 32 and 33. The outlet end of the water pump 31 is connected to the nozzle 2. In this embodiment, the control valve 34 is a three-way control valve.

[0042] In an optional embodiment, the first water inlet pipe 32 and the second water inlet pipe 33 may also be connected to the water inlet end of the water pump 31 via a one-way control valve instead of the control valve 34.

[0043] A dirt level detector is installed at the water outlet 21 of nozzle 2 to detect the degree of dirt on the surface of an object. In this embodiment, see [reference needed]. Figure 3 The dirt level detector is a color detector 6. The color detector 6 is used to detect the color of the surface of the object being cleaned. The color detector 6 can use known devices, which will not be described in detail here.

[0044] Example of cleaning method for water tank of oral irrigator:

[0045] The water tank cleaning method of the oral irrigator in this embodiment is the method applied to the oral irrigator in the above embodiment.

[0046] See Figure 4In this embodiment, the water tank cleaning method of the oral irrigator is performed as follows: First, step S1 is executed, controlling the oral irrigator to enter a preset water tank cleaning mode. Control valve 34 closes the first water inlet pipe 32 and opens the second water inlet pipe 33. Water pump 31 draws cleaning liquid from the second liquid tank 5 and sprays it out as a high-pressure liquid jet from nozzle 2. The cleaning liquid includes detergent or water; preferably, the cleaning liquid is water. During normal oral irrigator use, the first liquid tank 4 is mainly filled with water; therefore, the first liquid tank 4 needs to be cleaned. To clean the first liquid tank 4, it is first removed from the main body 1, and water is simultaneously added to the second liquid tank 5 so that the water in the second liquid tank 5 can be used to clean the first liquid tank 4. When it is necessary to control the oral irrigator to enter the preset water tank cleaning mode, this can be controlled via the oral irrigator's control button. When the preset water tank cleaning mode is entered, since the first water inlet pipe 32 cannot take in water, the control valve 34 closes the first water inlet pipe 32 and opens the second water inlet pipe 33, so that the water pump 31 can draw water from the second liquid tank 5 to clean the first liquid tank 4.

[0047] Next, step S2 is executed, controlling nozzle 2 to clean the first liquid tank 4. When cleaning the first liquid tank 4, nozzle 2 can be inserted into the first liquid tank 4, such as... Figure 5 As shown, the high-pressure water jet ejected from the nozzle 2 is used to clean the dirt in the first liquid tank 4.

[0048] In this embodiment, when controlling the nozzle 2 to clean the first liquid tank 4, the method further includes: using a dirt level detector to detect the degree of dirt on the inner wall surface of the first liquid tank 4; and controlling the water pressure of the nozzle 2 according to the degree of dirt. To facilitate reasonable control of the water pressure of the nozzle 2, it is necessary to control it based on the degree of dirt inside the first liquid tank 4. Using a dirt level detector to determine the degree of dirt inside the first liquid tank 4 and controlling the water pressure of the nozzle 2 based on the degree of dirt improves the rationality of the water pressure and enhances the cleaning effect.

[0049] In this embodiment, the dirt level detector is a color detector 6. The steps of detecting the dirt level of the inner wall surface of the first liquid tank 4 using the dirt level detector include: acquiring color information of the inner wall surface of the first liquid tank 4 using the color detector 6; matching the color information acquired by the color detector 6 with preset color information to confirm the dirt level. The preset color information can be pre-set using experimental data. Matching the color information acquired by the color detector 6 with the preset color information can improve the accuracy of the dirt level determination.

[0050] As described above, the water tank cleaning method of the oral irrigator of the present invention involves removing the first liquid tank 4 from the main body 1 and filling the second liquid tank 5 with water. The control valve 34 closes the first water inlet pipe 32 and opens the second water inlet pipe 33. The water pump 31 draws water from the second liquid tank 5 and sprays a high-pressure water jet from the nozzle 2. The second liquid tank 5 provides cleaning water to clean the first liquid tank 4, which ensures the cleanliness of the cleaning water. At the same time, the detachable nature of the first liquid tank 4 makes it easy for the nozzle 2 to be inserted into the first liquid tank 4 for all-round cleaning, thereby improving the cleaning effect of the water tank.

[0051] Example of a method for controlling the cleaning of a water flosser:

[0052] The teeth cleaning control method of the water flosser in this embodiment is the method applied in the water flosser of the above embodiment. Specifically, the first liquid tank 4 is filled with clean water, and the second liquid tank 5 is filled with plaque revealing agent.

[0053] See Figure 6 In this embodiment, when the oral irrigator's teeth cleaning control method is executed, firstly, step S11 is performed to determine whether a teeth spraying command has been obtained. When a teeth cleaning operation is required, a plaque revealing agent needs to be sprayed onto the teeth first. The plaque revealing agent can be used to spray the teeth, and when the plaque comes into contact with the plaque revealing agent, it will change color, usually to purplish-red. The depth of color is related to the amount of plaque. The degree of tooth staining can be determined by the color change. Therefore, it is necessary to confirm whether a teeth spraying command has been obtained. The teeth spraying command can be obtained through the corresponding control button.

[0054] If no tooth spraying command is received, proceed to step S11 to continuously detect the tooth spraying command. If a tooth spraying command is received, proceed to step S12, where control valve 34 closes the first water inlet pipe 32 and opens the second water inlet pipe 33, controlling nozzle 2 to spray plaque revealing agent for tooth spraying. Entering the tooth spraying mode, control valve 34 first closes the first water inlet pipe 32 and opens the second water inlet pipe 33, controlling nozzle 2 to spray plaque revealing agent onto the teeth to develop the plaque on the teeth.

[0055] After applying the plaque revealing agent to the teeth, step S13 is executed to determine if a cleaning instruction has been received. The cleaning instruction can be obtained via the corresponding control button. Since a cleaning operation is required after applying the plaque revealing agent, it is necessary to confirm that a cleaning instruction has been received.

[0056] If no cleaning instruction is received, proceed to step S13 to continuously detect the cleaning instruction. If a cleaning instruction is received, proceed to step S14, using the color detector 6 to detect the color of the indicator on the teeth, and determine the water pressure of nozzle 2 based on the indicator color. To facilitate control of the water pressure of nozzle 2, it is necessary to obtain the color of the indicator on the teeth to confirm the degree of tooth staining. Different shades of color represent different amounts of plaque; the darker the color, the more plaque there is, therefore, a higher water pressure from nozzle 2 is required. Therefore, the water pressure of nozzle 2 can be set according to the shade of color.

[0057] In this embodiment, the step of detecting the indicator color of the teeth using the color detector 6 includes: detecting the indicator color level of all teeth, and using the color corresponding to the tooth with the highest indicator color level as the indicator color. Using the color corresponding to the tooth with the highest indicator color level as the indicator color can improve the rationality of the water pressure output.

[0058] After determining the water pressure at the nozzle 2, step S15 is executed. Control valve 34 opens the first inlet pipe 32 and closes the second inlet pipe 33. Based on the water pressure, water pump 31 is controlled to draw clean water from the first liquid tank 4 for teeth rinsing. Once the water pressure at the nozzle 2 is determined, water pump 31 can be used to control the water pressure at the nozzle 2. Of course, to avoid wasting water during teeth rinsing, the water spray can be stopped and started via a control button.

[0059] Of course, in order to allow users enough time to check the color of the tooth indicator, step S15 can be executed only after the preset time for the teeth cleaning instruction is received, or a button confirmation instruction can be received before executing step S15 to confirm that the color of the tooth indicator has been checked before executing step S15.

[0060] As can be seen from the above, the teeth cleaning control method of the oral irrigator of the present invention injects plaque revealing agent into the second liquid tank 5, first controls the nozzle 2 to spray plaque revealing agent on the teeth, and then uses a color detector 6 to detect the color of the revealing agent on the teeth. Based on the color of the revealing agent, the water pressure of the nozzle 2 is determined, thereby improving the rationality of the water pressure and improving the teeth cleaning effect.

[0061] Example of a mouthwash control method for water flossers:

[0062] The mouthwash control method of the water flosser in this embodiment is the method applied in the water flosser of the above embodiment. Specifically, the first liquid tank 4 is filled with clean water, and the second liquid tank 5 is filled with mouthwash.

[0063] See Figure 7In this embodiment, when the mouthwash control method of the oral irrigator is executed, firstly, step S21 is performed to determine whether a command to enter the mouthwash mode has been obtained. The command to enter the mouthwash mode can be obtained through the corresponding control button.

[0064] If no command to enter the gargling mode is received, step S21 continues to be executed to continuously detect the command. If a command to enter the gargling mode is received, step S22 is executed to control the opening of the first water inlet pipe 32 and the second water inlet pipe 33 according to the preset mixing ratio of clean water and mouthwash. After entering the gargling mode, in order to meet the user's needs for gargling stimulation, the user can set the preset mixing ratio as needed, for example, the preset mixing ratio of clean water and mouthwash is set to 2:1. After determining the preset mixing ratio, the control valve 34 can be driven to control the opening of the first water inlet pipe 32 and the second water inlet pipe 33, so that clean water and mouthwash can enter the water pump 31 to mix at the preset mixing ratio.

[0065] Next, step S23 is executed, controlling nozzle 2 to spray mouthwash for rinsing. When rinsing is required, the water pump 31 can be controlled by the control switch to extract clean water and mouthwash in a preset mixing ratio and spray it into the user's mouth through nozzle 2.

[0066] In this embodiment, after receiving the command to enter the rinsing mode, the method further includes: obtaining the number of rinsing operations within a preset time period; and sending a prompt message when the number of rinsing operations exceeds a preset number. The preset time period and preset number of rinsing operations can be preset based on experimental data. By obtaining the number of rinsing operations within the preset time period and sending a prompt message when the number of rinsing operations exceeds the preset number, excessive use of mouthwash can be avoided, which could irritate the oral cavity, harm beneficial oral microorganisms, disrupt the balance of bacteria in the oral cavity, and thus prevent oral diseases.

[0067] In this embodiment, when controlling the nozzle 2 to spray mouthwash for rinsing, the method further includes: determining whether an instruction to adjust the preset mixing ratio is received; if so, adjusting the opening of the first water inlet pipe 32 and the second water inlet pipe 33 according to the instruction. To meet user habits and improve user experience, when controlling the nozzle 2 to spray mouthwash for rinsing, the preset mixing ratio can also be adjusted to adjust the intensity of the mouthwash to meet the user's needs.

[0068] As can be seen from the above, the mouthwash control method of the oral irrigator of the present invention injects clean water into the first liquid tank 4, injects mouthwash into the second liquid tank 5, and controls the opening of the first water inlet pipe 32 and the second water inlet pipe 33 according to the preset mixing ratio of clean water and mouthwash. This makes it easy to control the mixing degree of clean water and mouthwash, avoids mouthwash irritating the oral cavity, and improves mouthwash comfort.

[0069] It should be noted that the above are only preferred embodiments of the present invention, but the design concept of the invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept also fall within the protection scope of the present invention.
