Detailed implementation mode

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two components. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] According to a first aspect, an embodiment of the present utility model discloses a nozzle assembly, such as Figure 1-7As shown in the figure, it includes: a dental irrigator nozzle 1, a nozzle barrel 2, and a nozzle plug 3 arranged in sequence; the dental irrigator nozzle 1 is rotationally clamped with the nozzle barrel 2, one end of the nozzle plug 3 is embedded in the nozzle barrel 2 and fixedly connected to the nozzle barrel 2, and the other end of the nozzle plug 3 is installed on an external dental irrigator main body; a water outlet channel 11 is provided in the dental irrigator nozzle 1, the nozzle plug 3 is provided with a cavity 31 communicated with the water outlet channel 11, and a functional pill 5 for increasing the functionality of the nozzle assembly is placed in the cavity 31. In this embodiment, the functional pill 5 can be a whitening pill, a breath freshening pill, or a medicine pill, etc. According to the functional requirements required by the user, the corresponding functional pill 5 is configured into the nozzle assembly. The nozzle barrel 2 and the nozzle plug 3 can be fixedly bonded or ultrasonically welded.

[0030] It should be noted that by placing the functional pill 5 for increasing the functionality of the nozzle assembly in the cavity 31, the cavity 31 is communicated with the water outlet channel 11, the water flow enters from the bottom of the cavity 31 to impact the functional pill 5, and the formed functional liquid is sprayed out from the water outlet channel 11. Furthermore, a nozzle assembly and a dental irrigator are provided, which increase the functionality of the nozzle assembly and meet the actual functional requirements of users.

[0031] In the specific implementation process, a clamping block 21 is provided in the nozzle barrel 2, and a clamping groove 14 rotationally clamped with the clamping block 21 is provided on the dental irrigator nozzle 1. The number of the clamping block 21 and the clamping groove 14 is set to two, and the clamping block 21 and the clamping groove 14 correspond to each other one by one. A step 22 for facilitating the installation of the nozzle plug 3 is provided in the nozzle barrel 2.

[0032] As Figure 3 and Figure 7 shown, the cavity 31 includes a first cavity 311 and a second cavity 312 that communicate with each other, and the functional pill 5 is placed in the first cavity 311.

[0033] As Figure 3 shown, one end of the dental irrigator nozzle 1 is embedded in the cavity 31. It should be noted that since one end of the dental irrigator nozzle 1 is embedded in the cavity 31, it can prevent the high-pressure water from directly impacting the nozzle barrel 2, prevent the nozzle barrel 2 from cracking, and extend the service life of the nozzle barrel 2.

[0034] As Figure 3 and Figure 4 shown, a sealing ring 4 that abuts against the inner wall of the cavity 31 is sleeved on the dental irrigator nozzle 1. It should be noted that the sealing ring 4 plays a sealing role and can effectively waterproof the nozzle assembly.

[0035] As Figure 3 and Figure 4 shown, the sealing ring 4 is arranged in an O shape.

[0036] As Figure 1-5 shown, a convex bone 12 is provided at one end of the dental irrigator nozzle 1 located inside the nozzle barrel 2.

[0037] As Figure 1-5 shown, the number of the convex ribs 12 is set to be multiple, and the multiple convex ribs 12 are distributed at intervals along the circumferential direction of the oral irrigator nozzle 1. In this embodiment, through the arrangement of the convex ribs 12, the functional pellet 5 is prevented from blocking the water inlet of the water outlet channel 11, ensuring the smooth discharge of the functional liquid and realizing functional tooth cleaning.

[0038] As Figure 1-5 shown, the outer wall of the oral irrigator nozzle 1 is provided with rib bones 13. In the specific implementation process, the rib bones 13 and the oral irrigator nozzle 1 are of an integrally formed structure. Due to the arrangement of the rib bones 13, it is convenient for the user to rotate the oral irrigator nozzle 1, which is convenient for operation, saves manpower, and enhances the user experience.

[0039] As Figure 3 and Figure 7 shown, one end of the nozzle plug 3 is provided with an annular installation groove 32. In this embodiment, due to the arrangement of the installation groove 32, it is convenient to perform snap - on installation on the nozzle assembly.

[0040] According to a second aspect, an embodiment of the present utility model discloses an oral irrigator, including the nozzle assembly as in the first aspect. It should be noted that due to the arrangement of the nozzle assembly, different functional pellets 5 can be configured in the nozzle assembly to realize the flushing of different functional liquids, which also increases the flushing function of the oral irrigator and meets the various functional requirements of users.

[0041] Obviously, the above - mentioned embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creation of the present utility model.
