In some embodiments, the mouthwash can be concentrated mouthwash.

[0029] In some embodiments, one end of the first housing 11 can be provided with an opening 110, and the inside of the first housing 11 can be hollow, and the first cavity 111 can be formed in the inside of the first housing 11. The first cavity 111 can be a cylindrical cavity, and the capacity of the first cavity 111 can be greater than the capacity of the second cavity 121. In some embodiments, the housing 10 can be provided with a water filling channel, which can be in communication with the first cavity 111 to supply the first liquid (such as clean water) to the first cavity 111. In other embodiments, the water filling channel can be omitted. The first housing 11 can be detachably connected to the second housing 12, and by detaching the first housing 11 from the second housing 12, water can be filled into the first cavity 111 through the opening 110.

[0030] In some embodiments, the second housing 12 can be partially embedded in the first housing 11, specifically, the second housing 12 can be partially embedded in the first housing 11 from the opening 110. The second housing 12 and the first housing 11 can be in close contact through interference fit, so as to prevent the first liquid (such as clean water) in the first cavity 111 from leaking out. In other embodiments, a sealing structure can be provided between the inner wall of the first housing 11 and the outer wall of the second housing 12 to seal the gap therebetween. In some embodiments, the sealing structure can be a sealing ring or a sealing sleeve, such as a silica gel ring or a silica gel sleeve. The sealing structure can be in interference fit with the first housing 11 and the second housing 12.

[0031] ​In some embodiments, the second housing 12 can have a mounting cavity 120 formed therein for mounting the pump core assembly 20. The second cavity 121 can be formed in the second housing 12 and separated from the mounting cavity 120. In some embodiments, a separation wall can be formed in the second housing 12 to separate the second cavity 121 from the mounting cavity 120. In some embodiments, the second cavity 121 can have a liquid outlet 1211. The liquid outlet 1211 can be formed on the separation wall of the second housing 12 that defines the second cavity 121. In some embodiments, the second housing 12 can have a through hole 122 formed therein for the nozzle 30 to pass through. The through hole 122 can be formed on the end of the second housing 12 that is away from the first housing 11.

The liquid injection hole 123 can be in communication with the second cavity 121 and can be used to inject a second liquid (e.g. mouthwash) into the second cavity 121. In some embodiments, the liquid injection hole 123 can be formed on the end of the second housing 12 that is away from the first housing 11. The liquid injection hole 123 can be sealed by a sealing plug 14. The sealing plug 14 can be inserted into the liquid injection hole 123 to seal the liquid injection hole 123 after the injection of the second liquid (e.g. mouthwash) is completed to prevent the second liquid (e.g. mouthwash) from leaking out.

[0032] In some embodiments, the housing 10 can have an air exchange valve 13 formed therein. The air exchange valve 13 can be in communication with the second cavity 121 and can be used to exchange air in the second cavity 121 to facilitate the output of the second liquid (e.g. mouthwash) in the second cavity 121. In some embodiments, the air exchange valve 13 can be formed on the second housing 12. The air exchange valve 13 can be a conventional one-way valve that allows air to enter the second cavity 121 to balance the air pressure in the second cavity 121 and prevents the second liquid (e.g. mouthwash) from leaking out.

[0033] In some embodiments, the pump core assembly 20 can be disposed in the second housing 12 and can be disposed along the axial direction of the second housing 12. In some embodiments, the pump core assembly 20 can have a liquid inlet end 20a and a liquid outlet end 20b. The first cavity 111 can be disposed at the liquid inlet end 20a of the pump core assembly 20. The second cavity 121 can be disposed at one side of the pump core assembly 20 and can be higher than the liquid outlet end 20b of the pump core assembly 20. When a user holds the oral irrigator to clean the oral cavity, the second liquid (e.g. mouthwash) in the second cavity 121 can not pass through the pump core assembly 20.

[0034] In some embodiments, the nozzle 30 can be detachably connected with the pump core assembly 20, and in particular, can be fixed with the pump core assembly 20 through a card insertion cooperation or a threaded connection. When the oral irrigator is not needed to be used or the nozzle 30 needs to be replaced, the nozzle 30 can be detached from the pump core assembly 20, thereby reducing the cost of using the oral irrigator and avoiding the nozzle 30 from being contaminated to maintain the cleanliness of the nozzle 30. When the oral irrigator needs to be used, the nozzle 30 can be assembled with the pump core assembly 20.

[0035] In some embodiments, the oral irrigator can further include a first pipeline 40, which can be arranged at the liquid inlet end 20a of the pump core assembly 20. In some embodiments, the first pipeline 40 can be in communication with the liquid inlet end 20a and the first cavity 111. In some embodiments, the first pipeline 40 can be arranged to extend into the first cavity 111 from the opening 110, and an end of the first pipeline 40 extending into the first cavity 111 can be provided with a counterweight 50, which can be a counterweight ball or a counterweight block. When the pump core assembly 20 is turned on, the first pipeline 40 can output the first liquid (such as clean water) in the first cavity 111.

[0036] In some embodiments, the oral irrigator can further include a second pipeline 60, which can be in communication with the liquid outlet end 20b and the nozzle 30. In some embodiments, the second pipeline 60 can be integrally formed with the nozzle 30, that is, the second pipeline 60 can be integrated on the nozzle 30 or can be an integral structure with the nozzle 30. Of course, it can be understood that in other embodiments, the second pipeline 60 can also be a separate structure from the nozzle 30, and the nozzle 30 can be connected to an end of the second pipeline 60 away from the pump core assembly 20. In some embodiments, a connecting port 61 can be arranged on a side wall of the second pipeline 60, which can be used to access the second liquid (such as mouthwash) in the second cavity 121.

[0037] In some embodiments, the oral irrigator can further include a third pipeline 70, which can be in communication with the second pipeline 60 and the second cavity 121. In particular, one end of the third pipeline 70 can be connected to the connecting port 61, and the other end can be connected to the liquid outlet 1211. When the pump core assembly 20 is turned on, the third pipeline 70 can output the second liquid (such as mouthwash) in the second cavity 121 to the second pipeline 60, mix with the first liquid (such as clean water) delivered to the second pipeline from the first cavity 111, and then be output from the nozzle 30 for oral cleaning of a user. In particular, when the pump core assembly 20 is turned on, the negative pressure generated in the third pipeline 70 due to the communication between the third pipeline 70 and the second pipeline 60 can deliver the second liquid (such as mouthwash) in the second cavity 121 to the second pipeline 60.

[0038] The third pipeline 70 can be arranged at least partially in a bent manner. By arranging the third pipeline 70 at least partially in a bent manner, the second liquid (e.g. mouthwash) can be prevented from flowing to the pump core assembly 20 when the pump core assembly 20 is not turned on, thereby reducing the failure rate of the pump core assembly again. When the third pipeline 70 does not store liquid, the third pipeline 70 can output a small amount of air to the second pipeline 60 to mix with the first liquid (e.g. clean water) in the second pipeline, so that the liquid sprayed from the nozzle 30 after mixing has micro-bubbles, thereby making the user feel less irritating and improving the user's comfort.

[0039] The third pipeline 70 can include a first pipe segment 71 and a second pipe segment 72. One end of the first pipe segment 71 can be connected to the second pipeline 60, specifically, the first pipe segment 71 can be connected to the connecting port 61. The other end of the first pipe segment 71 can extend towards the liquid inlet end 20a and be arranged in an inclined manner. One end of the second pipe segment 72 can be connected to the end of the first pipe segment 71 away from the second pipeline 60, and the second pipe segment 72 can be arranged at a set angle with the second pipeline 60, and the other end of the second pipe segment 72 can extend towards the second cavity 121. In some embodiments, the set angle can be an acute angle, which can be greater than zero degrees and less than ninety degrees, such as forty-five degrees. In some embodiments, the third pipeline 70 as a whole can be V-shaped. In other embodiments, the third pipeline 70 can not be limited to including two pipe segments, and in other embodiments, the third pipeline 70 can include three pipe segments, four pipe segments, etc. In some embodiments, the angles formed between the pipe segments are not limited to being acute angles, but can also be rounded angles. The third pipeline 70 can also be a hose and can be generally wave-shaped.

[0040] In some embodiments, the oral irrigator can further include a control circuit connected to the pump core assembly 20, and a power supply connected to the control circuit.

[0041] When the pump core assembly 20 is turned on, the first pipeline 40 can output the first liquid (e.g. clean water) in the first cavity 111 to the second pipeline 60, and at the same time, the third pipeline 70 can output the second liquid (e.g. mouthwash) in the second cavity 121 to the second pipeline 60, and the second liquid (e.g. mouthwash) can mix with the first liquid (e.g. clean water) in the second pipeline 60 and then be sprayed from the nozzle 30.

[0042] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application; it should be pointed out that for ordinary skilled persons in the art, the above technical features can be freely combined without departing from the concept of the present application, and some deformations and improvements can be made, which all belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
