In some embodiments, a jack 111 is provided on the main body 10, which can be provided at one end of the water pump 11, for connecting with the nozzle 20, so that the nozzle 20 is in communication with the water pump 11.

[0027] As Figure 3 and Figure 4 shown, in some embodiments, the nozzle 20 can include a spray rod 21 and a spray head 22, the spray rod 21 can be connected with the spray head 22, in particular, the spray head 22 can be arranged at one end of the spray rod 21. The other end of the spray rod 21 can be connected with the main body 10, in particular, the spray rod 21 is partially inserted into the insertion hole 111 and can be fixedly connected with the insertion hole 111 by insertion. In some embodiments, the spray head 22 can be in communication with the spray rod 21 and can spray water flow. In some embodiments, the spray head 22 and the spray rod 21 can be an integral structure and can be integrally formed by injection molding. Of course, it can be understood that in other embodiments, the spray head 22 and the spray rod 21 can also be a split structure and can be connected and fixed by setting a plug-in structure, a threaded structure, etc.

[0028] In some embodiments, the spray rod 21 is provided with a first channel 210, which can extend from one end of the spray rod 21 to the other end of the spray rod 21 and can be in communication with the spray head 22. The first channel 210 can be used for water flow.

[0029] In some embodiments, the spray rod 21 is a tubular structure with both ends through. The spray rod 21 includes a first rod body 211 and a second rod body 212 arranged in a bent manner, wherein the first rod body 211 can be generally conical or circular truncated cone in appearance and can be arranged to expand away from the second rod body 212. The second rod body 212 is connected to one end of the first rod body 211 and can be arranged in a bent manner with the first rod body 211. In some embodiments, the first rod body 211 and the second rod body 212 can be integrally formed, and the first rod body 211 and the second rod body 212 can be formed by partially bending the spray rod 21. By arranging the first rod body 211 and the second rod body 212 in a bent manner, it can be better to stretch into the oral cavity and align the cleaning area, and it is also beneficial to adjust the cleaning angle. In other embodiments, the first rod body 211 and the second rod body 212 can also be a split structure and can be connected and fixed by insertion, threaded connection, etc. In some embodiments, the first channel 210 can pass through from one end of the first rod body 211 away from the second rod body 212 to the other end of the second rod body 212 connected with the spray head 22.

[0030] In some embodiments, the spray rod 21 is provided with a plug shaft 213 at an end away from the spray head 22, which can be arranged at an end of the first rod body 211 away from the second rod body 212. The plug shaft 213 can be inserted into the insertion hole 111. In some embodiments, the nozzle 20 can be rotatably connected with the main body 10, that is, the nozzle 20 can be arranged opposite to the main body 10 in rotation, so that the angle of the nozzle 20 can be adjusted by rotating the nozzle 20 or the main body 10, thereby facilitating the flushing of residues in the dental crevice and improving the cleanliness of the oral cavity. Specifically, the plug shaft 213 can be inserted into the insertion hole 111 and connected with the insertion hole 111 in rotation. The plug shaft 213 can be in interference fit or clearance fit with the insertion hole 111. The plug shaft 213 can be provided with a limiting structure 2131 arranged on the outer periphery of the plug shaft 213, which can be arranged on the annular protrusion on the outer periphery of the plug shaft 213, and the outer diameter thereof can be greater than the inner diameter of the insertion hole 111, thereby serving as a limiting function.

[0031] In other embodiments, the spray rod 21 can be connected and fixed with the insertion hole 111 through threaded connection, and the relative rotation of the nozzle 20 and the main body 10 can also be achieved. In other embodiments, the nozzle 20 can also be fixedly connected with the main body 10, that is, the nozzle 20 can be in a fixed direction, and the user can adjust the direction of the nozzle 20 by adjusting the holding direction.

[0032] In some embodiments, the spray head 22 can include at least two extension portions 221, specifically two extension portions 221, one end of the two extension portions 221 being connected to one end of the spray rod 21, and the two extension portions 221 being arranged at a set angle. Of course, it can be understood that in other embodiments, the extension portions 221 can not be limited to two, but can be multiple, such as three, four, etc. One end of the multiple extension portions 221 is connected, and the two extension portions 221 arranged opposite to each other can be arranged at an angle. In some embodiments, the at least two extension portions 221 can be integrally formed. Specifically, all the extension portions 221 can be integrally formed, which can be integrally formed by injection molding.

[0033] Each extension portion 221 has an inner surface 2211 and an outer surface 2212 opposite to the inner surface 2211. The inner surface 2211 of each extension portion 221 is connected with one end of the inner surface of another extension portion 221 at a set angle. The inner surface 2211 refers to the surface inside the angle. The angle of the set angle can be greater than or equal to 45 degrees and less than or equal to 135 degrees. In some embodiments, the set angle can be 90 degrees. In other embodiments, the angle of the set angle can also be 60 degrees, 120 degrees, etc.

[0034] In some embodiments, the inner surface of each extension 221 is provided with a spray hole 2213, which in some embodiments is a circular through hole, but it is understood that in other embodiments the spray hole 2213 can also be a square hole, a diamond hole or other shapes.

[0035] The central axis of the spray hole 2213 of each extension 221 intersects with the central axis of the spray hole 2213 of another extension 221, so that the water streams sprayed from the spray holes 2213 of at least two extensions 221 impact each other and form air-entrained water streams after mixing with air, thereby improving the cleaning range while ensuring the comfort of cleaning.

[0036] In some embodiments, the extension 221 is provided with a second channel 2214, one end of the second channel 2214 of each extension 221 communicates with the first channel 210, and the other end communicates with the spray hole 2213, the water stream output by the first channel 210 is respectively distributed to each second channel 2214 and then sprayed from the spray hole 2213.

[0037] It is understood that the above embodiments only express the preferred embodiments of the present application, which are described in more detail and in more detail, but cannot be construed as limiting the scope of the present application; it should be noted that for those skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and several modifications 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.
