[0031] A nasal irrigator is a tool used to clean the nasal cavity. It uses a water pump to direct the liquid in the water tank into the nozzle, which then sends the liquid into one nostril, flows through the nasal vestibule, sinuses, nasal passages, bypasses the nasopharynx, and then is discharged from the other nostril or from the mouth. Through the above paths, with the help of the impact force of the saline water flow, the pathogenic bacteria and dirt that have accumulated in the nasal cavity are discharged, so that the nasal cavity can restore its normal physiological environment, restore the self-detoxification function of the nasal cavity, and achieve the purpose of protecting the nasal cavity.

[0032] Currently, the nozzle assembly of the nasal irrigator is usually of integrated design. Therefore, the shielding cover that contacts the user's nasal cavity cannot be removed from the nozzle body, resulting in the user being unable to replace the shielding cover according to the size of his or her own nasal cavity.

[0033] To achieve the above purpose, please refer to Figures 1 to 4 The nozzle assembly proposed by the utility model comprises:

[0034] A nozzle 110 having a water outlet end 112 for spraying liquid; and

[0035] The shielding cover 120 is detachably connected to the water outlet 112 . The shielding cover 120 is penetrated by a liquid channel 120 a communicating with the water outlet 112 . The liquid channel 120 a is used to allow liquid to flow out.

[0036] In this embodiment, by designing the shielding cover 120 and the nozzle 110 body to be detachable, the user can not only select the shielding cover 120 according to his or her own needs, but also design the shape of the shielding cover 120 so that the shielding cover 120 can enter the ear, so that the nozzle assembly can be used on the ear flusher to achieve the function of one machine with multiple uses.

[0037] Specifically, in this embodiment, the shielding cover 120 is provided with an external thread, the water outlet end 112 is provided with an internal thread, and the shielding cover 120 is threadedly connected to the water outlet end 112, so that the shielding cover 120 and the nozzle 110 can be detachably connected, and the threaded connection improves the stability of the connection between the two. In addition, the shielding cover 120 can optionally be provided with a snap-on protrusion, and the water outlet end 112 is provided with a snap-on groove, so that the shielding cover 120 and the water outlet end 112 are snap-on, and in other embodiments, the connection method between the shielding cover 120 and the nozzle 110 is not limited, and it is only necessary to realize the detachable connection between the shielding cover 120 and the nozzle 110.

[0038] In one embodiment, please refer to Figure 2 and Figure 3 One end of the shielding cover 120 is connected to the water outlet end 112 , and the outer diameter of the end of the shielding cover 120 away from the water outlet end 112 decreases in a direction away from the water outlet end 112 .

[0039] In this embodiment, the variable diameter design of the shielding cover 120 facilitates the user to insert the shielding cover 120 into the nasal cavity, so that the liquid channel 120a of part of the shielding cover 120 enters the user's nasal cavity, and the water sprayed by the nozzle 110 flows through the liquid channel 120a, and then enters one side of the user's nasal cavity from the liquid channel 120a, and the water flows out from the other side of the user's nasal cavity, completing a nasal cleaning operation.

[0040] Specifically, in order to improve the user experience, the shielding cover 120 is made of odorless and elastic silicone or rubber material, so that when the shielding cover 120 is located in the user's nasal cavity, the foreign body sensation in the user's nasal cavity is reduced. Furthermore, the side surface of the shielding cover 120 away from the water outlet 112 is a curved surface, which better fits the user's nasal cavity and improves the aesthetics of the shielding cover 120.

[0041] In one embodiment, please refer to Figure 3 The shielding cover 120 includes a connecting portion 121 and an inserting portion 122 connected to each other, a portion of the water outlet end 112 is interference fit with the inner wall of the connecting portion 121 , and an outer diameter of the inserting portion 122 decreases in a direction away from the connecting portion 121 .

[0042] In this embodiment, the connection part 121 is preferably made of silicone or rubber, so that the water outlet 112 is interference-fitted with the inner wall of the connection part 121 through the elastic deformation of the connection part 121, eliminating the need to set a model of a clamping protrusion or an external thread, and reducing the cost of designing a mold for the enterprise. The water outlet 112 is interference-fitted with the inner wall of the connection part 121, realizing the functions of plug-and-play, disassembly and separation, and simplifying the steps for users to replace the shielding cover 120.

[0043] In one embodiment, please refer to Figure 4 The liquid channel 120 a forms a plurality of water outlets 122 a at one end of the inserting portion 122 away from the connecting portion 121 , and the plurality of water outlets 122 a are evenly distributed along the circumference of the inserting portion 122 .

[0044] In this embodiment, a plurality of water outlets 122a are provided on the insertion portion 122 located in the user's nasal cavity to slow down the speed and impact force of the water flow sprayed from the nozzle 110, thereby reducing the discomfort caused to the user by the excessive speed and impact force of the water flow. Specifically, there are three water outlets 122a, and the three water outlets 122a are evenly distributed along the circumference of the insertion portion 122, that is, the angle between every two water outlets 122a is 120°. The arrangement of the water outlets 122a improves the aesthetics of the shielding cover 120.

[0045] In one embodiment, please refer to Figure 2 and Figure 4 The outer diameter of the connecting portion 121 is smaller than the outer diameter of the inserting portion 122 , and a through hole 122 b is formed through the outer edge of the inserting portion 122 along the opening direction of the liquid channel 120 a , and the through hole 122 b and the liquid channel 120 a are independent of each other.

[0046] In this embodiment, the size of the connection part 121 only needs to be sufficient to connect with the water outlet end 112 of the nozzle 110, so the outer diameter of the connection part 121 is smaller than the outer diameter of the insertion part 122, which reduces the volume of the connection part 121, thereby reducing the weight of the shielding cover 120 and reducing the fatigue of the user caused by the excessive weight of the irrigator 100. The insertion part 122 is provided with a through hole 122b so that the user can maintain normal breathing during the nasal flushing process.

[0047] In one embodiment, please refer to Figure 4 There are multiple through holes 122 b , and the hole wall of the through hole 122 b has three sections of arc surfaces connected to each other. The multiple through holes 122 b are evenly opened along the circumference of the insertion portion 122 .

[0048] In this embodiment, a plurality of through holes 122b are evenly provided along the circumference of the inserting portion 122, thereby improving the aesthetics of the shielding cover 120. In other embodiments, the shape of the through holes 122b is not limited.

[0049] In one embodiment, a limiting protrusion is provided on the water outlet end 112 , a limiting groove is provided in the shielding cover 120 , the limiting protrusion is located in the limiting groove, and the limiting protrusion is used to restrict the shielding cover 120 from rotating relative to the water outlet end 112 .

[0050] In this embodiment, the cooperation between the limiting protrusion and the limiting groove prevents the shielding cover 120 from rotating relative to the nozzle 110 when the water flow sprayed from the nozzle 110 sprays into the liquid channel 120a during use.

[0051] In one embodiment, please refer to Figure 1 and Figure 2 The nozzle 110 has a water inlet end 113 connected to the water outlet end 112, and the angle between the water inlet end 113 and the water outlet end 112 is greater than 90° and less than 180°.

[0052] In one embodiment, please refer to Figure 1 A nozzle decoration ring 1131 is provided on the outer edge of the water outlet end 112, and the nozzle decoration ring 1131 is used to abut against the fuselage.

[0053] In this embodiment, the nozzle decorative ring 1131 is used to cover the gap between the water inlet end 113 of the nozzle 110 and the body, so as to improve the aesthetics of the washer 100 when the nozzle assembly is assembled with the washer 100. Specifically, the nozzle 110 decorative ring and the water inlet end 113 are integrally formed.

[0054] The present utility model also proposes a flusher 100, which includes a nozzle assembly. The specific structure of the nozzle assembly refers to the above-mentioned embodiment. Since the flusher 100 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0055] In this embodiment, the flusher 100 also includes an outer shell and a body. The outer shell includes a horizontal portion and a vertical portion connected to each other. The horizontal portion and the vertical portion are connected in a "7" shape. The vertical portion is connected to the body. The horizontal portion is used to install a power supply.
