Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0045] In the description of the present application, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0046] A power pump is provided in a personal care spraying device (such as a dental irrigator, a nasal irrigator, etc.) to provide power for the flow of liquid in the liquid path of the personal care spraying device, so that the liquid is ejected from the nozzle of the personal care spraying device to achieve the cleaning function.

[0047] However, the nozzle structure currently adopted by personal care spraying devices is not reasonably designed, and there are problems such as unstable flushing water flow and easy interruption of the flushing water flow, resulting in a poor use experience of the personal care spraying device.

[0048] To solve the above technical problems, the present application provides a nozzle and a personal care spraying device, aiming to improve the stability of the liquid flow output by the personal care spraying device, avoid the interruption of the liquid flow, maintain a strong flushing force, improve the flushing effect and the user experience of the personal care spraying device.

[0049] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0050] Please refer to Figures 1 to 3 , Figure 1 which is a module schematic diagram of the nozzle provided by the present application, Figure 2 which is a schematic structural diagram of the nozzle at a first angle in an embodiment provided by the present application, Figure 3 which is a cross-sectional schematic diagram of the nozzle provided by the present application.

[0051] As Figures 1 to 3 shown, the nozzle 1 includes a nozzle head 10, a nozzle tube 20 and a connecting portion 30. The nozzle head 10 forms a liquid outlet 11. The nozzle tube 20 is connected to the nozzle head 10 and forms a liquid flow channel 24 communicating with the liquid outlet 11. The connecting portion 30 is connected to one end of the nozzle tube 20 away from the nozzle head 10 and is used for connecting and adapting to the main body of the personal care spraying device. The connecting portion 30 forms a liquid inlet channel 31 communicating with the liquid flow channel 24.

[0052] Among them, the nozzle tube 20 forms at least a first bending portion 25 and a second bending portion 26, and the bending properties of the first bending portion 25 and the second bending portion 26 are different. The bending properties include at least one of the bending angle and the bending direction;

[0053] Specifically, the liquid input from the side close to the connecting portion 30 to the liquid inlet channel 31 will sequentially pass through the liquid inlet channel 31 and the liquid flow channel 24 and be ejected from the liquid outlet 11. More specifically, when the main body of the personal care spraying device is connected and adapted to the connecting portion 30 of the nozzle 1, the main body of the personal care spraying device can output liquid through the nozzle 1, and the liquid output by the main body passes through the liquid inlet channel 31 and the liquid flow channel 24 and is ejected from the liquid outlet 11 to form an outgoing liquid flow, so as to flush the target position.

[0054] It should be noted that the above personal care spraying device includes but is not limited to at least one of a dental irrigator, a nasal irrigator and an electric toothbrush. Correspondingly, the main body of the personal care spraying device can spray and flush the target positions such as the oral cavity, tooth gaps and nasal cavity of an individual through the nozzle 1, so as to realize convenient personal care.

[0055] It should also be noted that the liquid includes but is not limited to water, physiological saline, mouthwash, and is not limited herein.

[0056] It can be understood that the bending attributes of the first bending portion 25 and the second bending portion 26 are different. Specifically, it can be: the bending directions of the first bending portion 25 and the second bending portion 26 are different, the bending angles of the first bending portion 25 and the second bending portion 26 are different, or the bending directions of the first bending portion 25 and the second bending portion 26 are different and the bending angles are different.

[0057] For example, in Figure 2 and Figure 3 in the nozzle 1 shown, the first bending portion 25 and the second bending portion 26 at least have different bending directions. For example, in Figure 2 from the corresponding first perspective, the bending direction of the first bending portion 25 is to the left, and the bending direction of the second bending portion 26 is to the right.

[0058] Based on the first bending portion 25 and the second bending portion 26 formed at the nozzle tube 20, the liquid input by the main body of the personal care spraying device into the nozzle 1 undergoes two-stage flow buffering and then is sprayed out through the nozzle tube 20. Compared with the existing nozzle 1, the liquid flow can be further buffered, so that the liquid flow sprayed out by the nozzle tube 20 is continuous without interruption and maintains a strong flushing force, improving the stability of the personal care spraying device when outputting the liquid flow, avoiding the situation where the liquid flow sprayed out by the nozzle tube 20 is interrupted, and thus improving the flushing effect and the use experience of the personal care spraying device.

[0059] As Figure 2 and Figure 3 shown, in some embodiments, the nozzle tube 20 includes a first tube section 21, a second tube section 22 and a third tube section 23. The first tube section 21 is connected to the connecting portion 30, the third tube section 23 is connected to the nozzle head 10, and the second tube section 22 is disposed between the first tube section 21 and the third tube section 23;

[0060] wherein, the second tube section 22 is connected to the first tube section 21 and forms the first bending portion 25, the second tube section 22 is connected to the third tube section 23 and forms the second bending portion 26, and moreover, the first tube section 21 forms a first flow channel 241, the second tube section 22 forms a second flow channel 242, the third tube section 23 forms a third flow channel 243, and the first flow channel 241, the second flow channel 242 and the second flow channel 242 form a liquid flow channel 24.

[0061] Specifically, the liquid input by the host into the liquid flow channel 24 through the liquid inlet channel 31 flows in the liquid flow channel 24 from the first flow channel 241 to the second flow channel 242, then to the third flow channel 243, and finally sprays out from the liquid outlet 11. Moreover, the liquid in the liquid flow channel 24 will be subject to the flow-attenuating effect of the first bending portion 25 and the second bending portion 26, so that the liquid flow sprayed out by the nozzle 20 is continuous without interruption and maintains a strong flushing force, improving the stability of the personal care spraying device when outputting the liquid flow, avoiding the situation where the liquid flow sprayed out by the nozzle 20 is interrupted, and thus enhancing the flushing effect and user experience of the personal care spraying device.

[0062] In some embodiments, the bending directions of the first bending portion 25 and the second bending portion 26 are different.

[0063] Specifically, the bending directions of the first bending portion 25 and the second bending portion 26 can be opposite or there is an included angle between the two bending directions.

[0064] For example, in Figure 2 the corresponding first perspective, the bending directions of the first bending portion 25 and the second bending portion 26 are opposite, the bending direction of the first bending portion 25 is to the left, the bending direction of the second bending portion 26 is to the right, and the overall shape of the nozzle 1 is "S" shaped.

[0065] It can be understood that the different bending directions of the first bending portion 25 and the second bending portion 26 facilitate the nozzle 1 to enter the deep parts of both sides of the oral cavity for flushing. Especially when the personal care spraying device is a dental irrigator, the different bending directions of the first bending portion 25 and the second bending portion 26 in the nozzle 20 can make the nozzle 20 enter the position close to the tooth gap, improving the flushing effect and user experience.

[0066] As Figure 3 shown in (b), in some embodiments, the bending angle A1 of the first bending portion 25 is greater than the bending angle A2 of the second bending portion 26.

[0067] It can be understood that the larger bending angle A1 of the first bending portion 25 and the smaller bending angle A2 of the second bending portion 26 strengthen the flow-attenuating effect of the nozzle 20 near the nozzle head 10, and make the liquid flow sprayed out by the nozzle 20 stable and continuous without interruption, improving the flushing effect and user experience.

[0068] It should be noted that the bending angle A1 of the first bending portion is specifically defined as: the included angle between the extending direction of the first pipe section 21 towards the connecting portion 30 and the extending direction of the second pipe section 22 towards the third pipe section 23; the bending angle A2 of the second bending portion is specifically defined as: the included angle between the extending direction of the second pipe section 22 towards the first pipe section 21 and the extending direction of the third pipe section 23 towards the nozzle 10. That is to say, the bending angle A1 of the first bending portion is the inner angle formed by the first pipe section 21 and the second pipe section 22, and the bending angle A2 of the second bending portion is the inner angle formed by the second pipe section 22 and the third pipe section 23.

[0069] In some embodiments, the bending angle A1 of the first bending portion 25 is 150° to 175°; and / or, the bending angle A2 of the second bending portion 26 is 90° to 135°.

[0070] Taking the nozzle 1 applied to a dental irrigator or an electric toothbrush as an example, it can be understood that limiting the bending angle A1 of the first bending portion 25 to be 150° to 175° first makes it easy for the spray pipe 20 to enter the depths of both sides of the oral cavity for cleaning, and the relatively large bending angle A1 of the first bending portion 25 is convenient for the processing and forming of the first pipe section 21 and the second pipe section 22, making the outer wall surface of the spray pipe 20 smooth, especially the outer wall of the first bending portion 25.

[0071] It can also be understood that limiting the bending angle A1 of the second bending portion 26 to be 90° to 135° can enable the liquid flow output by the spray pipe 20 to be ejected directly towards the tooth surface and in a direction slightly above during the process of cleaning teeth, avoiding the ejection angle of the water flow from deviating from the tooth surface and the tooth gaps, and improving the cleaning effect.

[0072] In some embodiments, the first bending portion 25 is arranged in an arc shape, the second bending portion 26 is arranged in an arc shape, and the bending radius R1 of the first bending portion 25 is greater than the bending radius R2 of the second bending portion 26.

[0073] It can be understood that the buffering effect of the first bending portion 25 and the second bending portion 26 arranged in an arc shape on the liquid flow has little influence on the flushing force of the ejected liquid flow, and it is also convenient for the processing and forming of the first pipe section 21, the second pipe section 22 and the third pipe section 23, making the outer wall surfaces of the first bending portion 25 and the second bending portion 26 smooth.

[0074] Preferably, the ratio of the bending radius R1 of the first bending portion 25 to the bending radius R2 of the second bending portion 26 is 1.2 to 3.5.

[0075] In some embodiments, the length L1 of the first pipe section 21 is greater than the length L2 of the second pipe section 22, and the length L2 of the second pipe section 22 is greater than the length of the third pipe section 23;

[0076] Alternatively, the length L1 of the first pipe section 21 is greater than the length L2 of the second pipe section 22, and the length L2 of the second pipe section 22 is greater than the sum L3 of the lengths of the third pipe section 23 and the nozzle 10.

[0077] It should be noted that Figure 3 (b) The length indicated by L3 is specifically the distance from the second bending portion 26 to the liquid outlet 11 of the nozzle 1, that is, the sum of the lengths of the third pipe section 23 and the nozzle 10. Exemplarily, the length L2 of the second pipe section 22 is greater than the length of the third pipe section 23. Further, the length L2 of the second pipe section 22 is also greater than the sum L3 of the lengths of the third pipe section 23 and the nozzle 10.

[0078] It can be understood that defining the length L1 of the first pipe section 21 to be greater than the length L2 of the second pipe section 22, and the length L2 of the second pipe section 22 to be greater than the length of the third pipe section 23 can make the flow of the liquid remain gentle near the liquid outlet 11, and avoid the liquid flow being cut off due to the flow retardation of the first bending portion 25 and the second bending portion 26 on the liquid flow.

[0079] Preferably, the ratio of the length of the first pipe section 21 to the length of the second pipe section 22 is 1.5 to 3.

[0080] Preferably, the ratio of the length of the second pipe section 22 to the third pipe section 23 is 1.2 to 3; or, the ratio of the length of the second pipe section 22 to the sum of the lengths of the third pipe section 23 and the nozzle 10 is 1.2 to 3.

[0081] In some embodiments, the flow channel diameter of the first flow channel 241 is greater than or equal to the flow channel diameter of the second flow channel 242; and / or, the flow channel diameter of the second flow channel 242 is greater than or equal to the flow channel diameter of the third flow channel 243.

[0082] It should be noted that the flow channel diameter of the first flow channel 241 is proportional to the cross-sectional area of the first flow channel 241. The larger the flow channel diameter of the first flow channel 241, the larger the cross-sectional area of the first flow channel 241. The same applies to the second flow channel 242 and the third flow channel 243.

[0083] It should be understood that the flow channel diameter of the first flow channel 241 closer to the connection portion 30 is larger, and the flow channel diameter of the third flow channel 243 closer to the nozzle 10 is smaller, so that during the process of the liquid flow flowing in the spray pipe 20 towards the nozzle 10, the pressure of the liquid flow increases, thereby enabling the ejected liquid flow to have a stronger flushing force.

[0084] For example, the relationship of the flow channel diameters of the first flow channel 241, the second flow channel 242, and the third flow channel 243 can be: the flow channel diameter of the first flow channel 241 is the same as that of the second flow channel 242, and the flow channel diameters of the first flow channel 241 and the second flow channel 242 are greater than that of the third flow channel 243; or, the flow channel diameter of the first flow channel 241 is greater than those of the second flow channel 242 and the third flow channel 243, and the flow channel diameters of the second flow channel 242 and the third flow channel 243 are the same; or, the flow channel diameter of the first flow channel 241 is greater than that of the second flow channel 242, and the second flow channel 242 is greater than that of the third flow channel 243; or, the flow channel diameters of the first flow channel 241, the second flow channel 242, and the third flow channel 243 are the same.

[0085] Exemplarily, in order to make the nozzle 20 easy to form and the connection between the first pipe section 21, the second pipe section 22, and the third pipe section 23 smooth, the flow channel diameter of the first flow channel 241 can be set to be equal to that of the second flow channel 242, and the flow channel diameter of the second flow channel 242 can be set to be equal to that of the third flow channel 243. In particular, the flow channel diameter of the first flow channel 241 near one end of the first bending portion 25 is equal to that of the second flow channel 242 near one end of the first bending portion 25, and / or, the flow channel diameter of the second flow channel 242 near one end of the second bending portion 26 is equal to that of the third flow channel 243 near one end of the second bending portion 26.

[0086] In some embodiments, the flow channel diameter of the first flow channel 241 gradually decreases from the end adapted to the connecting portion 30 to the end corresponding to the end adapted to the second pipe section 22;

[0087] and / or, the flow channel diameter of the second flow channel 242 gradually decreases from the end adapted to the first pipe section 21 to the end corresponding to the end adapted to the third pipe section 23;

[0088] and / or, the flow channel diameter of the third flow channel 243 gradually decreases from the end adapted to the second pipe section 22 to the end corresponding to the end adapted to the nozzle 10.

[0089] It can be understood that defining the flow channel diameters of the first flow channel 241, the second flow channel 242, and the third flow channel 243 to gradually decrease in the corresponding directions can make the pressure of the liquid flow gradually increase during the process of the liquid flow flowing in the nozzle 20 towards the nozzle 10, so that the ejected liquid flow has a strong flushing force.

[0090] Exemplarily, the flow channel diameters of the first flow channel 241 and the second flow channel 242 can be made the same to facilitate the forming of the first and second flow channels, and the flow channel diameter of the third flow channel 243 can be gradually decreased from the end adapted to the second pipe section 22 to the end corresponding to the nozzle 10, so that the liquid flow ejected from the liquid outlet 11 has a strong flushing force.

[0091] Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of the second angle of the nozzle 1 in an embodiment provided by the present application.

[0092] As Figure 4 shown, in some embodiments, the first pipe section 21, the second pipe section 22 and the third pipe section 23 are all arranged on the same target plane a-a, and the target plane a-a is the plane where the first bending portion 25 is located or the plane where the second bending portion 26 is located.

[0093] For example, in the nozzle as Figure 2 , Figure 3 shown, the bending direction of the first bending portion 25 is opposite to the bending direction of the second bending portion 26, then the first bending portion 25 and the second bending portion 26 are in the same plane, the plane where the first bending portion 25 and the second bending portion 26 are located is the target plane a-a, and the extending directions of the first pipe section 21, the second pipe section 22 and the third pipe section 23 are all parallel to the target plane a-a.

[0094] It should be understood that arranging the first pipe section 21, the second pipe section 22 and the third pipe section 23 on the same target plane a-a is conducive to the processing and forming of the spray pipe 20. The first bending portion 25 and the second bending portion 26 can be processed on the spray pipe 20 by means of hot bending to form the first pipe section 21, the second pipe section 22 and the third pipe section 23.

[0095] Please refer to Figure 5 , Figure 5 which is a schematic structural diagram of the nozzle 1 in another embodiment provided by the present application.

[0096] As Figure 5 shown, in some embodiments, bristles 12 or protrusions are arranged on the periphery of the nozzle 10 corresponding to the liquid outlet 11.

[0097] Specifically, the bristles 12 or protrusions can be used to brush the target position, so as to brush the target position in addition to flushing the target position, increasing the optional oral and nasal cavity cleaning methods for the user and improving the cleaning effect of the nozzle 1. Among them, the bristles 12 can be flexible bristles 12, and the protrusions can also be flexible protrusions.

[0098] It should be noted that the bristles 12 or protrusions can be arranged on at least part of the periphery corresponding to the liquid outlet 11. Exemplarily, in Figure 5In the shown nozzle 10, the bristles 12 are arranged corresponding to the entire circumferential side of the liquid outlet 11, so that the nozzle 1 can brush the target position from multiple angles, improving the cleaning effect.

[0099] As Figures 1 to 5 shown, in some embodiments, the nozzle 10 is detachably connected to the spray pipe 20, or the nozzle 10 and the spray pipe 20 are integrally formed; and / or, the spray pipe 20 and the connecting part 30 are integrally formed.

[0100] Specifically, the way that the nozzle 10 and the spray pipe 20 are integrally arranged can be that the nozzle 10 and the third pipe section 23 are integrally formed; the way that the spray pipe 20 and the connecting part 30 are integrally formed can be that the first pipe section 21 and the connecting part 30 are integrally formed. Further, the integral formation of the nozzle 10 and the spray pipe 20, and the integral formation of the spray pipe 20 and the connecting part 30 can be realized by means such as welding and gluing.
