[0002] An oral irrigator is an auxiliary tool for oral cleaning that uses a pulsed water flow to clean teeth and the spaces between teeth. Portable irrigators are particularly popular among users due to their portability and compact size.

[0039] DETAILED DESCRIPTION

[0040] The preferred embodiments described below are for illustrative purposes only, and those skilled in the art may readily conceive of other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0041] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0042] The present invention provides a multifunctional oral irrigator control system, which performs integrated control on a switching valve, a water supply system, a ventilation and drying system, etc. in the multifunctional oral irrigator.

[0043] The following is a description of the hardware of the multi-function water flosser:

[0044] First see Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The multifunctional water flosser comprises a water flosser body 8 and a multifunctional base 1. The water tank 81 of the water flosser body 8 is connected to the connecting nozzle 111 of the base. The water flosser body 8 is arranged on the base for hydration or drying. Specifically, the water flosser body 8 can be selected from any water flosser on the market, and the bottom of its water tank 81 is modified to form a one-way channel at the bottom of the water tank 81. The one-way channel is controlled by a spring-loaded one-way valve and the connecting nozzle 111. After the connecting nozzle 111 is inserted into the spring-loaded one-way valve, a channel is formed to facilitate further hydration or ventilation and drying. Preferably, the top edge of the connecting nozzle 111 has a notch 1111, and the notch 1111 is to prevent the spring-loaded one-way valve from blocking the connecting nozzle 111.

[0045] For further information, see Figure 5The multifunctional base includes a base housing 1, a switching valve 6, a water supply system, and a ventilation and drying system. The base housing 1 serves as a basic structural carrier to facilitate the placement of the oral irrigator body 8. Whether the switching valve 6, water supply system, and ventilation and drying system are located inside or outside the base housing 1 is not restricted in the present invention. In this embodiment, the switching valve 6, water supply system, and ventilation and drying system are all located inside the base housing 1.

[0046] The switching valve 6 is designed to connect the water supply system and the connecting nozzle 111, or to connect the ventilation and drying system and the connecting nozzle 111. Specifically, the water supply system and the ventilation and drying system are both connected to one end of the switching valve 6, while the other end of the switching valve 6 is connected to the connecting nozzle 111. When the water tank 81 of the irrigator body 8 is placed on the connecting nozzle 111, the switching valve 6 can be used to select whether to ventilate and dry the water tank 81 of the irrigator body 8 for antibacterial purposes or to replenish water. This allows the base to provide at least two functions within the same main channel structure, resulting in a simple and convenient structure.

[0047] The irrigator body 8 comprises a mechanism assembly, a nozzle 83, and a water tank 81. The mechanism assembly draws water from the water tank 81, and the nozzle 83, mounted therein, sprays water in a pulsed stream. The top of the water tank 81 has a water inlet, capped with a top cover. This is the principle of conventional technology for the irrigator body 8, so detailed description is omitted. However, those skilled in the art will readily appreciate that this principle is essential for understanding the technical solutions of the present invention.

[0048] The base shell 1 includes a base upper cover 11 and a base bottom cover 12, which form the base shell 1 and have a waterproof cavity inside. Part or all of the structures of the water supply system, the conversion valve 6 and the ventilation and drying system are arranged in the waterproof cavity.

[0049] The switching valve 6 functions as a "switch gate." When the water supply system is connected to the connecting nozzle 111, the water tank 81 of the dental irrigator body 8 is replenished with water, while the ventilation and drying system is shut off. When the ventilation and drying system is connected to the connecting nozzle 111, the water tank 81 of the dental irrigator body 8 is dried and ventilated, while the water supply system is shut off. Because the switching valve 6 is a three-way solenoid valve with two inputs and one output, the water supply system and the ventilation and drying system are connected to the two input ports of the solenoid valve, respectively, while the connecting nozzle 111 is connected to the output port of the solenoid valve via a pipe.

[0050] See also Figure 3 and Figure 5The water supply system includes a water supply tank 24, a first water inlet nozzle 21, and a first water pump 23, and each component is connected through a first water pipe 22. Specifically, the first water inlet nozzle 21 is provided on the base housing 1, the water supply tank 24 is mounted on the first water inlet nozzle 21, and the first water pump 23 is connected to the first water inlet nozzle 21 and the conversion valve 6 through the first water pipe 22.

[0051] Furthermore, a first water inlet nozzle 21 is disposed on the base cover 11, and a first water pump 23 is disposed within the waterproof cavity within the base housing 1. The first water inlet pipes include at least two pipes: one connecting the first water pump 23 to the first water inlet nozzle 21 to facilitate metered water extraction from the water supply tank 24, and one connecting the first water pump 23 to the solenoid valve. The first water pump 23 can pump water from the water supply tank 24 into the water tank 81 of the irrigator body 8 at a predetermined metered rate for replenishment, and the metered water replenishment is controllable and configurable.

[0052] Furthermore, to facilitate water supply from the water supply tank 24, a first one-way valve is installed at the opening of the water supply tank 24. The water supply tank 24 is mounted to the first water inlet 21 via the first one-way valve. When the water supply tank 24 is installed with the opening facing downward on the first water inlet 21, the first water inlet 21 pushes open the first one-way valve, forming a water flow channel for water supply. Preferably, the first one-way valve is a common spring-loaded one-way valve available on the market.

[0053] In addition to hydration and drying and ventilation functions, the oral irrigator body 8 is also gradually shifting to other functional areas such as oral care. To this end, this embodiment provides a preferred implementation, in which the base shell 1 is also equipped with a functional liquid supply function. This functional liquid includes but is not limited to cleaning liquid, medical solution, etc.

[0054] The functional liquid supply mechanism includes a functional liquid container 34, a second water inlet nozzle 31, and a second water pump 33. The second water inlet nozzle 31 is provided on the base housing 1, the functional liquid container 34 is mounted on the second water inlet nozzle 31, and the second water pump 33 mixes the functional liquid into the water supply system through the second water pipe 32.

[0055] Specifically, the second water inlet nozzle 31 is located on the base cover 11, and the second water pump 33 is located in the waterproof cavity within the base housing 1. The second water inlet pipes include at least two: one connecting the second water pump 33 to the second water inlet nozzle 31 to facilitate metered extraction of functional liquid from the functional liquid container 34, and one connecting the second water pump 33 to the first water pipe 22. The second water pump 33 can pump functional liquid from the functional liquid container 34 into the first water pipe 22 at a predetermined rate for mixing. The metering of the functional liquid is controllable and configurable. Furthermore, when the first water pump 23 is shut down, the second water pump 33 can connect to the solenoid valve through the first water pipe 22 to replenish the functional liquid independently.

[0056] For example: when the functional liquid is cleaning liquid, the mixing ratio of the two is controlled by setting the metering flow rate ratio of the first water pump 23 and the second water pump 33. The functional liquid is mixed with the water in the first water pipe 22 through the second water pipe 32, and then enters the solenoid valve to be replenished in the water tank 81 of the oral irrigator body 8; or when replenishing the cleaning liquid alone, the first water pump 23 does not work, the second water pump 33 works alone and is connected to the solenoid valve through the first water pipe 22, and then enters the solenoid valve to be replenished in the water tank 81 of the oral irrigator body 8.

[0057] Furthermore, to facilitate liquid supply to the functional liquid container 34, a second one-way valve is installed at the container opening of the functional liquid container 34. The functional liquid container 34 is mounted to the second water inlet nozzle 31 via the second one-way valve. When the functional liquid container 34 is mounted on the second water inlet nozzle 31 with the container opening facing downward, the second water inlet nozzle 31 pushes open the second one-way valve, forming a water flow channel for water supply. Preferably, the second one-way valve is a common spring-loaded one-way valve available on the market.

[0058] Similarly, the water tank 81 of the irrigator body 8 has an opening at the bottom, which is equipped with a third one-way valve. The water supply tank 24 is mounted to the connecting nozzle 111 via the third one-way valve. When the water supply tank 24 is mounted on the connecting nozzle 111 with the opening facing downward, the connecting nozzle 111 pushes open the third one-way valve, forming a water flow channel for water supply. Preferably, the third one-way valve is a common spring-loaded one-way valve.

[0059] In winter, cold water is more irritating to the human oral cavity, so warm water is more suitable for rinsing teeth. A heating system 5 is also provided on the base housing 1. This system heats at least the water supply system. Specifically, the heating system 5 can heat the water supply system alone to produce warm water, heat the cleaning solution alone, or heat a mixture of cleaning solution and cold water. The location of the heating system 5 determines the type of heating function it provides.

[0060] For further information, see Figure 6 The heating system 5 includes a heat pipe 51 and a heating film 52 or a heating wire. This embodiment describes the heating system 5 as including the heat pipe 51 and the heating film 52. The heating film 52 is coated on the outer wall of the heat pipe 51. The heat pipe 51 is at least connected to the water supply system, and heats the water when it flows through. For the three heating modes mentioned above, in conjunction with the structural form of the heating system 5, there are two installation positions for the heating system 5:

[0061] First, the heating system 5 is installed in the water supply system, and the heat pipe 51 is connected to the first water pipe 22. The heat pipe can be connected between the first water inlet 21 and the first water pump 23, or between the first water pump 23 and the solenoid valve. The purpose is to heat the cold water of the water supply system so that when the cleaning liquid is mixed, the temperature of the mixed liquid will not drop significantly.

[0062] Secondly, the heating system 5 is installed after the water supply system and the functional fluid supply mechanism have mixed. The heat pipe 51 is connected to the first water pipe 22. In this case, the heat pipe is located between the first water pump 23 and the solenoid valve, and after the first water pipe 22 and the second water pipe 32 have mixed. The purpose of the heat pipe is to heat the mixed liquid or heat the functional fluid separately when replenishing the functional fluid.

[0063] Preferably, the heat pipe 51 is made of a fully thermally conductive metal and includes a water inlet 511 and a water outlet 512. A turbulence chamber 514 is provided within the internal cavity between the water inlet 511 and the water outlet 512. The turbulence chamber 514 is composed of a plurality of spoilers 513. Preferably, the spoilers 513 are also made of thermally conductive metal and can be heated by the heating film 52. The heating pipe 51 has two functions. On the one hand, when heating a mixed liquid, the turbulence chamber 514 can further mix the liquid, making the mixing more uniform. On the other hand, because the heat-conducting spoilers 513 are provided, the liquid can be heated more efficiently.

[0064] Preferably, the heating film 52 is a metal flexible film heater, which is a bendable film heating sheet that can be attached to and wrapped around the outer wall of the heat pipe 51. Heat is generated about ten seconds after the original switch of the heater is turned on, and the heating efficiency is high.

[0065] The water in the water supply tank 24 is used for oral rinsing, so high hygiene requirements are required. A preferred embodiment of this embodiment also includes a sterilization system, which is installed in the water supply system to sterilize and disinfect. Preferably, the sterilization system is a UV germicidal lamp 4, which sterilizes and disinfects the water through ultraviolet light. Furthermore, the UV germicidal lamp 4 can be installed inside the water supply tank 24, or in the first water pipe 22, or as a separate component connected to the first water pipe 22 for water flow. Regardless of the above method, its function is to sterilize the water flow.

[0066] Of course, when connected to the first water pipe 22 or arranged in the first water pipe 22, it can also be positioned after the functional liquid supply mechanism mixes with the water flow to directly sterilize the mixed liquid. It is also convenient to sterilize the functional liquid in the functional liquid supply mechanism when it needs to be sterilized.

[0067] After the water is replenished and the user rinses their teeth, the irrigator body 8 needs to be dried and sterilized before the next use. Therefore, after rinsing the teeth, a ventilation and drying system is required for drying and sterilization. To this end, a preferred embodiment of this embodiment is that the ventilation and drying system includes a drying fan 7, an air duct and an air inlet. The air inlet is provided on the base shell 1, and the drying fan 7 is connected to the air inlet and the conversion valve 6 through the air duct. Preferably, the drying fan 7 is a centrifugal fan, including a turbocharged air volume method, which can provide a large air volume for ventilation and drying.

[0068] Specifically, after the irrigator is finished, the water tank 81 opening of the irrigator body 8 is aligned with the connecting nozzle 111 and inserted. The solenoid valve is then opened for ventilation and drying. At this time, the water supply system and / or the functional liquid supply mechanism are closed. Even if there is water accumulated in the water tank 81 of the irrigator body 8, it will not flow back into the water supply system and / or the functional liquid supply mechanism. The drying fan 7 then boosts the pressure and sends air into the water tank 81 of the irrigator body 8 through the solenoid valve and the connecting nozzle 111 for ventilation and drying, blowing out the accumulated water and moist air from the water tank 81 water inlet. It should be noted that the water inlet is provided for both normal water replenishment (this is a necessary structure of the general irrigator body 8 on the market) and for facilitating the blowing of air after ventilation and drying.

[0069] For further information, see Figure 5 A wireless charging device is also provided on the base shell 1, which is located below the corresponding oral irrigator. The oral irrigator with wireless charging function can be charged through the charging coil 9.

[0070] In order to accurately control the amount of liquid added to the water flosser, a water level sensor is provided inside the water tank 81 of the water flosser to feed back the water level detection data in the water tank.

[0071] The following is a detailed description of the multi-function water flosser control system:

[0072] This system is an integrated control system, housed within base 1 and connected to an external power source. The main control module controls the water supply control module, ventilation and drying control module, and switching valve control module. Base 1 houses an integrated circuit board, and each control module processes and controls data using chips on the integrated circuit board. This is general computer technology, so the principles are not elaborated here. For the architectural model, please refer to 1.

[0073] Specifically, the water supply control module is used to control the water supply system of the above-mentioned water flosser. The water supply control module is connected to the main control module, and the control connection is achieved by an integrated circuit board. Preferably, the water supply control module is set in the first water pump 23 of the water supply system to control the operation of the first water pump 23. The water supply control module can also be an integrated circuit board, serving as the control main board of the first water pump.

[0074] The ventilation and drying control module is used to control the ventilation and drying system of the dental flosser. The ventilation and drying control module is connected to the main control module, and the control connection is achieved through an integrated circuit board. Preferably, the ventilation and drying control module is located within the drying fan 7 of the ventilation and drying control system to control the operation of the drying fan 7. The module itself can also be an integrated circuit board, serving as the main control board for the drying fan 7.

[0075] Furthermore, the ventilation and drying control module has a time control unit, which is used to set the ventilation and drying time of the ventilation and drying system.

[0076] The switching valve control module controls the switching valve, switching the water supply system and the ventilation and drying system to communicate with the irrigator body 8. The switching valve control module is connected to the main control module, and the control connection is achieved by an integrated circuit board. Preferably, the switching valve control module is located within the switching valve 6 (i.e., the three-way solenoid valve) to control the operation of the solenoid valve. It can also be an integrated circuit board, serving as the main control board of the solenoid valve.

[0077] As mentioned above, the heating control module controls the heating system to heat the water supply, creating a warm water supply. This heating control module is connected to the main control module, with the control connection implemented by an integrated circuit board. Preferably, the heating control module is disposed within the heating film 52 to control the heating of the heating film 52. The module itself can also be an integrated circuit board, serving as the main control board for the heating film 52. If the heating film 52 is a metal flexible film heater wrapped around a heating tube, the heating control module should not be placed against the heating tube to prevent overheating and burnout.

[0078] The wireless charging control module is used for wireless charging of the dental implant body 8 by the wireless charging station on the base. The wireless charging control module is connected to the main control module and the control connection is realized by the integrated circuit board. Preferably, the wireless charging control module is set in the wireless charging station to realize the operation control of the charging coil 9 in the wireless charging station. The wireless charging control module can also be an integrated circuit board as the control main board of the wireless charging station.

[0079] The water level feedback module is used to feedback water level sensor data from the water level sensor within the water flosser body 8. The water level feedback module is communicatively connected to the main control module. This communication connection can be achieved through protocols such as Bluetooth and Wi-Fi. Preferably, the water level feedback module is set in the water level sensor to realize water level detection and data feedback. It can also be an integrated circuit board, serving as the control motherboard of the water level sensor.

[0080] The sterilization control module is used to control the sterilization system to sterilize the water supply of the water supply system. The sterilization control module is connected to the main control module, and the control connection is realized by an integrated circuit board. Preferably, the sterilization control module is installed in the UV sterilization lamp 4 to realize the light sterilization operation of the UV sterilization lamp 4. It can also be an integrated circuit board, serving as the control main board of the UV sterilization lamp 4.

[0081] The control modules of the above components such as the first water pump, the second water pump, the conversion valve, the drying fan, and the wireless charging station are connected to the integrated circuit board circuit, or some water pumps, drying fans, etc. that are compatible with PLC connection can also be connected through PLC.

[0082] See also Figure 2 Combined with Figure 1 、 Figure 3 and Figure 4 The present invention also provides a control method for a multifunctional oral irrigator control system to control the multifunctional operation of the switching valve, water supply system, and ventilation and drying system on the oral irrigator body 8. The method mainly includes the following steps:

[0083] When the water flosser body 8 needs to be replenished with water, the main control module controls the water supply control module to start the water supply system to replenish the water to the water flosser body 8; and at the same time, the ventilation and drying control module is closed.

[0084] Specifically, when the water tank opening of the irrigator body 8 is mounted on the communication nozzle 111, the water level feedback module communicates with the main control module, i.e., the integrated circuit control board, via protocols such as Bluetooth and Wi-Fi. The water level sensor detects the water level in the water tank 81 and determines whether it is in a water shortage state. If so, it sends a water shortage signal to the main control module, which then controls the first water pump 23 to replenish water. Preferably, the main control module is an integrated circuit board (not shown in the accompanying drawings).

[0085] Before the first water pump 23 is operated, the user can set whether to heat the water supply, whether to replenish cleaning liquid at the same time, and whether to sterilize the water supply through the operation panel or operation keys on the base 1.

[0086] Specifically, the heating control module is controlled through an operation panel or operation key externally connected to the integrated circuit control board to turn on the heating plate in the heating system, thereby heating the water supply of the water supply system; the functional liquid supply control module is controlled to turn on the second water pump 33 in the functional liquid supply system, thereby supplying functional liquid and mixing it with the water supply of the water supply system; the sterilization control module is controlled to turn on the UV sterilization lamp 4 in the sterilization system to sterilize and disinfect the water supply of the water supply system.

[0087] The above three functions can be set individually or in combination.

[0088] Then, the first water pump 23 starts operating, and the switching valve 6 connects the water supply system to the connecting nozzle 111, replenishing the irrigator. The water level sensor detects a full state and sends a full water signal to the main control module, which stops replenishing water. It also stops the sterilization, mixing, and heating functions.

[0089] When the water flosser body 8 needs to be ventilated and dried, the main control module controls the ventilation and drying control module to start the ventilation and drying system to ventilate and dry the water flosser body 8; at the same time, the water supply control module is turned off.

[0090] Specifically, when the water tank opening of the irrigator body 8 is mounted on the communication nozzle 111, the water level feedback module communicates with the main control module (i.e., the integrated circuit control board) via protocols such as Bluetooth and WiFi. The water level sensor detects the water level in the water tank 81 and determines whether there is a water shortage. However, active intervention from the operation panel or operation keys can set the main control module to enter ventilation and drying control.

[0091] At this point, the main control module controls the switching valve 6 to switch the connection between the ventilation and drying system and the connection nozzle 111, and controls the drying fan 7 to perform ventilation and drying. Simultaneously, due to the characteristics of the switching valve (three-way solenoid valve), the water supply system and other systems involved in liquid replenishment are shut down. The pressurized airflow from the drying fan 7 blows any remaining water and moist air in the water tank 81 out of the water inlet. Simultaneously, a ventilation and drying timer is set; when the set time expires, ventilation automatically stops, providing a simple and convenient operation.

[0092] It should be noted that whenever the irrigator body 8 needs to be rehydrated or ventilated and dried, the charging coil 9 will sense the irrigator body 8 and automatically charge it when it is placed on the base. This eliminates the need for an external charging port, improves water resistance, and reduces the risk of electrical leakage.

[0093] Those skilled in the art will appreciate that the embodiments of the present invention described above are intended to be illustrative only and are not intended to limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
