[0058] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0060] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0061] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0062] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two), similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0063] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0064] The surface or interior of human organs or tissues is prone to breeding bacteria or attached dirt. At present, cleaning liquid sprayed by devices such as tooth irrigators and nasal irrigators is often used to rinse human organs or tissues.

[0065] However, when the user's organs or tissues become diseased or inflamed, more pathogens will be produced. The cleaning fluid sprayed by the oral care device cannot kill the pathogens in the organs or tissues, affecting the user's experience.

[0066] For example, when a user's oral cavity becomes diseased or inflamed, more germs will be produced. When a water flosser is used for flushing, the cleaning fluid sprayed by the water flosser cannot kill the germs in the oral cavity, resulting in the user being unable to maintain fresh breath.

[0067] In order to solve the above technical problems, the embodiments of the present application provide a nozzle and an oral care device, which can spray a second solvent and a first solvent that is different from the second solvent and has been atomized or cavitated. Under the joint action of the second solvent and the first solvent, the dirt on human organs or tissues can be cleaned and the germs on the organs or tissues can be killed, effectively improving the user experience. The oral care device includes but is not limited to an oral irrigator, an electric toothbrush or other handheld oral care devices. The embodiments of the present application do not specifically limit the type of oral care device.

[0068] See also Figures 1 to 3 and Figure 8 The oral care device may include a nozzle 1, and the nozzle 1 includes a nozzle head 100, a nozzle 200, and an ultrasonic transducer 321. The nozzle head 100 may include a second liquid outlet 1011 and a first liquid outlet 1021, and the nozzle 200 is connected to the nozzle head 100. The nozzle 100 may have a second flow channel 101 and a first flow channel 102 that are independent of each other; the second flow channel 101 may be connected to the second liquid outlet 1011, and the first flow channel 102 may be connected to the first liquid outlet 1021. The nozzle 200 may also have a water delivery channel 201 connected to the second flow channel 101. The ultrasonic transducer 321 is used to atomize or cavitate the first solvent in the first flow channel 102.

[0069] The ultrasonic transducer 321 can atomize the first solvent so that the first solvent is in a mist form, and thus is uniformly sprayed to the human organs or tissues such as the oral cavity and nasal cavity, which is beneficial to the absorption of the first solvent by the human body. The ultrasonic transducer 321 can also cavitate the first solvent. The first solvent vibrates under the influence of cavitation to produce tens of thousands of tiny bubbles, which are formed by the longitudinal propagation of ultrasonic waves and move to the target area with the jet of the first solvent. Compared with conventional direct flushing of the target area, the jet after ultrasonic cavitation has a higher cleaning power, so that the oral care device can also produce a stronger cleaning ability when the jet pressure of the first solvent is relatively low.

[0070] The solution provided in the present application provides a second solvent to the second flow channel 101 of the nozzle 200 and provides a first solvent to the first flow channel 102 of the nozzle 200, so that the second liquid outlet 1011 connected to the second flow channel 101 can spray out the second solvent, and the first solvent in the first flow channel 102 can be atomized or cavitated by the ultrasonic transducer 321, so that the first liquid outlet 1021 connected to the first flow channel 102 sprays out the atomized or cavitated first solvent different from the second solvent. Under the joint action of the second solvent and the first solvent, it is possible to effectively kill pathogens on organs or tissues while cleaning dirt in human organs or tissues, thereby improving the user experience.

[0071] In some embodiments, the nozzle 1 may further include a solvent tank 310. The solvent tank 310 may store a medicine, which may be at least one of a solid powder, a liquid, and a gas. The solvent tank 310 may be detachably connected to the nozzle 200 or may be an integral component. The detachable connection may facilitate replacement of the solvent tank 310 after damage, and the solvent tank 310 and the nozzle 200 as an integral component are more convenient to process.

[0072] In some embodiments, the oral care device may also include a device host, which includes a first liquid supply component (not shown in the figure) and a second liquid supply component (partially shown in the figure); the second liquid supply component can be connected to the second flow channel 101 to provide a second solvent; the first liquid supply component can be connected to the first flow channel 102 to provide a first solvent.

[0073] It should be noted that the oral care device mainly includes a nozzle 1 and a device body (not shown in the figure), and the nozzle 1 and the device body can be connected by snap connection, thread connection, magnetic connection or other methods to facilitate users to disassemble and install. The first liquid supply component and the second liquid supply component can be fully or partially arranged on the device body of the oral care device.

[0074] The second liquid supply assembly may include a liquid supply tank and a flushing pump disposed in the main body of the device. The liquid supply tank contains water or other second solvents having a cleaning effect. The flushing pump may be connected to the liquid supply tank and the water delivery channel 201. The flushing pump may suck the second solvent in the liquid supply tank and deliver the second solvent to the second flow channel 101 of the nozzle 200 through the water delivery channel 201 of the nozzle 200, and finally spray the second solvent through the second liquid outlet 1011 to act on human organs or tissues that need to be cleaned, such as the oral cavity, nasal cavity, etc.

[0075] See also Figure 1 and Figure 2 In some embodiments, the first liquid supply component may include a solvent tank 310 and a suction device (not shown in the figure). The suction device can connect the solvent tank 310 and the first flow channel 102, and is used to draw the first solvent in the solvent tank 310 into the first flow channel 102, and spray it through the first liquid outlet 1021 to act on human organs or tissues such as the oral cavity and nasal cavity that need to be cleaned.

[0076] An ultrasonic transducer is a device that converts electromagnetic energy into sound energy, and is usually made of magnetostrictive material. In some embodiments, the ultrasonic transducer may be a piezoelectric ceramic. Piezoelectric ceramics can utilize the piezoelectric effect of their materials to convert the sound energy of a power ultrasonic frequency source into mechanical vibrations, and radiate ultrasonic waves into the liquid through the working surface. The microbubbles in the liquid can maintain vibration under the action of ultrasonic waves. When the sound pressure or sound intensity reaches a critical value, the bubbles will expand rapidly and then suddenly close. A shock wave is generated at the moment of bubble closure, causing extremely high pressure and temperature to be instantly generated around the bubbles, resulting in a cavitation effect, which repeatedly impacts the dirt. Therefore, even when the impact force of the first solvent is small, a strong cleaning and sterilization ability can be produced.

[0077] The extraction device may be a drug delivery pump or an extraction member, and the drug delivery pump is similar to the flushing pump and will not be described in detail here. In some embodiments, the extraction device may be an extraction member, one end of which extends into the solvent tank 310, and the other end is arranged near the ultrasonic transducer 321. The extraction member can continuously supply the first solvent to the ultrasonic transducer 321, and the ultrasonic transducer 321 continuously atomizes or cavitates the first solvent, and sprays the atomized or cavitated first solvent from the first flow channel 102. Exemplarily, the extraction member may be a water-absorbing cotton strip or the like.

[0078] There are many positions where the suction member is disposed on the ultrasonic transducer 321. In some embodiments, the suction member can be disposed between the first liquid outlet 1021 and the ultrasonic transducer 321 at one end close to the ultrasonic transducer 321, or disposed on a side of the ultrasonic transducer 321 away from the first liquid outlet 1021; wherein the working direction of the ultrasonic transducer 321 is toward the first liquid outlet 1021.

[0079] In some embodiments, a plurality of micropores are provided in the working area of ​​the ultrasonic transducer 321. If the suction member is provided on the side of the ultrasonic transducer 321 away from the first liquid outlet 1021, the ultrasonic transducer 321 can atomize or cavitate the first solvent in the suction member, and the atomized or cavitated first solvent passes through the micropores in the working area of ​​the ultrasonic transducer 321 and is finally sprayed out from the first flow channel 102, thereby ensuring that the suction member is not exposed to the external environment and effectively preventing the suction member from being contaminated by the external environment.

[0080] In some embodiments, the working area of ​​the ultrasonic transducer 321 is not provided with micropores. If the suction member is arranged between the first liquid outlet 1021 and the ultrasonic transducer 321, the ultrasonic transducer 321 can atomize or cavitate the first solvent in the suction member and make the atomized or cavitated first solvent spray out from the first flow channel 102. By arranging the suction member in front of the ultrasonic transducer 321, it can ensure that the first solvent in the suction member is in full contact with the ultrasonic transducer 321, thereby improving the energy conversion efficiency of the ultrasonic transducer 321.

[0081] Regardless of whether it is arranged on either side of the ultrasonic transducer 321, the first solvent provided by the extraction member can be atomized or cavitated by the ultrasonic transducer 321. The extraction member is preferably arranged on the side of the ultrasonic transducer 321 away from the first liquid outlet 1021. Compared with being arranged between the first liquid outlet 1021 and the ultrasonic transducer 321, the extraction member will not block the ultrasonic transducer 321 and affect the performance of the ultrasonic transducer 321. The working direction of the ultrasonic transducer 321 is toward the first liquid outlet 1021, which can avoid the energy generated by the ultrasonic transducer 321 from being concentrated on the first liquid outlet 1021, and thus may act more on the target area, thereby improving the cleaning and sterilization effects.

[0082] It is understandable that there may be various structures of the nozzle 200 having the second flow channel 101, the first flow channel 102, the second liquid outlet 1011 and the first liquid outlet 1021. In some embodiments, two parallel through holes may be directly opened in the nozzle 200 to form the second flow channel 101, the first flow channel 102, the second flow channel 101 and the first flow channel 102.

[0083] In order to improve the working reliability of the nozzle 1, the embodiment of the present application also optimizes the design of the nozzle 200. Figure 3 to Figure 4 In some embodiments, the nozzle 200 may include a nozzle body 110 and an annular cover 130, the nozzle body 110 having a through hole 111 and an annular groove 113 surrounding the through hole 111; the through hole 111 penetrates the nozzle body 110 to form a first flow channel 102 and a first liquid outlet 1021; the annular cover 130 covers the annular groove 113 to form a second flow channel 101; and a second liquid outlet 1011 is provided on the annular cover 130.

[0084] The first flow channel 102 formed by the annular cover 130 and the annular groove 113 is annular. The first flow channel 102 can be connected to the water delivery channel 201 of the nozzle 200. After the first solvent delivered by the nozzle 200 enters the first flow channel 102, it can be divided into two branches and flow to the first liquid outlet 1021 at the same time. Even if one branch is blocked, the first solvent can also flow to the first liquid outlet 1021 from the other branch, thereby improving the working reliability of the nozzle 1.

[0085] See also Figure 3 and Figure 5 In some embodiments, the nozzle 1 further includes a liquid spraying member 140 , which is connected to the second liquid outlet 1011 and protrudes from the outer side of the annular cover 130 .

[0086] The first solvent of the second liquid outlet 1011 can be sprayed out through the liquid spraying member 140 .

[0087] In some embodiments, the liquid spraying member 140 and the annular cover 130 are detachably connected or are an integral component. Liquid spraying members 140 with different outlet sizes have different speeds and flow rates for spraying the first solvent. The liquid spraying member 140 and the annular cover 130 are detachably connected, which can facilitate users to select a suitable liquid spraying member 140 according to their needs. The liquid spraying member 140 and the annular cover 130 as an integral component can be manufactured by integral injection molding or the like, which is more convenient to process.

[0088] The installation position of the ultrasonic transducer 321 can be flexibly set, and can be set in the device body or in the nozzle 1. The effect of the ultrasonic transducer 321 on the atomization or cavitation of the first solvent will gradually weaken as the distance between the ultrasonic transducer 321 and the first liquid outlet 1021 increases. In order to make the ultrasonic transducer 321 closer to the first liquid outlet 1021, in some embodiments, the nozzle 200 has a accommodating cavity; the accommodating cavity is connected to the first flow channel 102; and the ultrasonic transducer 321 can be arranged in the accommodating cavity. In this way, the ultrasonic transducer 321 is closer to the first liquid outlet 1021, which is conducive to the atomization or cavitation of the first solvent by the ultrasonic transducer 321, and further improves the cleaning and sterilization performance of the oral care device.

[0089] See also Figure 3 and Figure 7 In some embodiments, the nozzle 200 may further include a seal 322, which is sealingly disposed on the wall of the accommodating cavity and is at least partially located between the first liquid outlet 1021 and the ultrasonic transducer 321; the seal 322 has a flow hole 3221 in the middle, and the ultrasonic transducer 321 has a plurality of micropores (not shown in the figure) corresponding to the flow hole 3221.

[0090] The seal 322 can wrap the ultrasonic transducer 321 to prevent moisture from entering the accommodating cavity from the first flow channel 102, causing corrosion on the working surface of the ultrasonic transducer 321. The flow hole 3221 corresponding to the seal 322 in the middle of the ultrasonic transducer 321 can be densely distributed with multiple micropores to facilitate the atomization or cavitation of the first solvent. The size of the flow hole 3221 can be flexibly set according to the distribution of the micropores on the ultrasonic transducer 321, which will not be described in detail here.

[0091] See also Figure 7 In some embodiments, the seal 322 has an installation cavity 3222 inside; the ultrasonic transducer 321 is accommodated in the installation cavity 3222, and a notch 3223 for wiring is opened on the side of the seal 322 away from the second liquid outlet 1011.

[0092] The ultrasonic transducer 321 can be conveniently and quickly fixed on the sealing member 322 through the mounting cavity 3222 , and the cable of the ultrasonic transducer 321 can be smoothly led out by providing a notch 3223 in the sealing member 322 .

[0093] In some embodiments, the contour shape of the ultrasonic transducer 321 can be the same as or similar to the cross-sectional contour shape of the mounting cavity 3222. It is understood that if the contour shape of the ultrasonic transducer 321 can be the same as or similar to the cross-sectional contour shape of the mounting cavity 3222, the ultrasonic transducer 321 can be more easily installed in the mounting cavity 3222. Exemplarily, the ultrasonic transducer 321 can be disc-shaped. It is understood that the shape of the ultrasonic transducer 321 is not limited thereto. In other embodiments, the ultrasonic transducer 321 can also be rectangular, annular or other structures. In addition, designers can select ultrasonic transducers 321 of different thicknesses according to actual needs, which are not specifically limited here.

[0094] Please continue to see Figure 7 In some embodiments, the notch 3223 is connected to the flow hole 3221. In this way, part of the seal 322 between the notch 3223 and the flow hole 3221 can be removed to avoid blocking the line of sight and provide more operating space for the user to install, replace the ultrasonic transducer 321 and route the ultrasonic transducer 321.

[0095] See also Figure 4 In some embodiments, the nozzle body 110 further has a groove 112 connected to the through hole 111; the groove 112 and the annular groove 113 are located on opposite sides of the nozzle body 110; the nozzle 200 may further include: an end cover 120, the end cover 120 covers the groove 112 to form a accommodating cavity.

[0096] By providing the groove 112, the ultrasonic transducer 321 can be conveniently installed on the nozzle body 110 from the groove 112. In addition, when the ultrasonic transducer 321 is damaged, the groove 112 and the end cover 120 can also facilitate the repair and replacement of the ultrasonic transducer 321.

[0097] In some embodiments, the end cap 120 may be provided with a sealing structure. When the end cap 120 is connected to the nozzle body 110, the end cap 120 can seal the side of the accommodating chamber away from the first liquid outlet 1021, thereby preventing the first solvent passing through the accommodating chamber from leaking from the side of the ultrasonic transducer 321 away from the first liquid outlet 1021.

[0098] See also Figure 6 In some embodiments, a first protrusion 121 pressing against the seal 322 and / or a second protrusion 122 pressing against the ultrasonic transducer 321 are provided on a side surface of the end cover 120 .

[0099] The structure of the first protrusion 121 is adapted to the structure of the sealing member 322. For example, when the sealing member 322 has only the flow hole 3221, the first protrusion 121 may be a circular ring, a semicircular ring or other structure that avoids the flow hole 3221. For another example, when the sealing member 322 has the flow hole 3221 and the notch 3223, see Figure 6 The first protrusion 121 may be a U-shaped structure that avoids the flow hole 3221 and the notch 3223. In order to avoid damaging the ultrasonic transducer 321, the force of the second protrusion 122 acting on the ultrasonic transducer 321 is evenly distributed. The second protrusion 122 may be Figure 6 In addition, the second protrusion 122 can be made of materials such as sponge and soft silicone.

[0100] The first protrusion 121 presses against the sealing member 322, and can fix the sealing member 322 in the accommodating cavity of the nozzle body 110. The second protrusion 122 presses against the ultrasonic transducer 321, and can tightly connect the ultrasonic transducer 321 and the sealing member 322.
