[0025] Figure 1 to Figure 2 Some preferred embodiments of the oral irrigator of the present invention are shown. The oral irrigator can be used for oral cleaning, and the temperature of the water flow sprayed therefrom can be adjusted, thereby meeting the needs of users and improving the comfort of users during oral cleaning. The oral irrigator has the advantages of simple structure and high user experience. The oral irrigator can be a handheld oral irrigator, and is easy to use.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, the oral irrigator may include an oral irrigator body 10 and a water storage structure 20 , wherein the oral irrigator body 10 can spray water for oral cleaning. The water storage structure 20 can be used to store water to supply water to the oral irrigator body 10 .

[0027] In some embodiments, the water flosser body 10 may include a shell 11, a core assembly 12, a nozzle 13, and a water inlet pipe 14. The shell 11 is used to install the core assembly 12 and can be assembled with the water storage structure 20. The core assembly 12 is disposed in the shell 11, and the core assembly 12 can be used to provide power so as to pump out the water in the water storage structure 20. The nozzle 13 can be disposed at one end of the shell 11 and can be connected to the core assembly 12. The nozzle 13 can be extended into the oral cavity to spray water into the oral cavity. The water inlet pipe 14 can be connected to the core assembly 12. The water inlet pipe 14 is located at one end of the shell 11 away from the nozzle 13, and at least part of it can be disposed in the water storage structure 20. Under the power of the core assembly 12, the water in the water storage structure 20 is output to the nozzle 13.

[0028] In some embodiments, the housing 11 may be roughly flat and may be made of plastic material. Of course, it is understandable that in some other embodiments, the housing 11 is not limited to being flat and may be cylindrical. In some embodiments, the housing 11 is not limited to being made of plastic material and may also be made of metal material, glass, etc. In some embodiments, a first mounting through hole 111 may be provided at one end of the housing 11 and a second mounting through hole 112 may be provided at the other end; the first mounting through hole 111 may allow the core assembly 12 to partially pass through and connect to the nozzle 13. The second mounting through hole 112 may be used for the water inlet pipe 14 to pass through.

[0029] like Figure 3 and Figure 4 As shown, in some embodiments, the movement assembly 12 may include a power pump 121 and a main board 122; the power pump 121 may be connected to the main board 122, and in some embodiments, the power pump 121 may be electrically connected to the injection plate 122. A connecting through hole 1211 may be provided at one end of the power pump 121, and the connecting through hole 1211 may be used to connect with the nozzle 13, and the nozzle 13 may be partially inserted into the connecting through hole 1211, and may be fixed with the connecting through hole 1211 by interference fit or thread connection. The main board 122 may be provided on one side of the power pump 121, and may be used to issue a start or shut down instruction to the power pump 121. The connection between the main board 122 and the power pump 121 and the control of the power pump 121 may be realized by using existing technologies. In some embodiments, a power supply structure (not shown) may be provided in the movement assembly 12, and the power supply structure (not shown) may be connected to the main board 122 to supply power to various components.

[0030] Further, in some embodiments, the nozzle 13 may include a spray rod 131 and a spray head 132, and one end of the spray rod 131 may be connected to the connecting through hole 1211 of the core assembly 12. The spray head 132 may be arranged at one end of the spray rod 131, and it may be bent with the spray rod 131. By bending the spray head 132 and the spray rod 131, it is beneficial for the spray head 132 to be aligned with the cleaning area. In some embodiments, a spray hole 1321 may be arranged on the spray head 132, and the spray hole 1321 may be one. It is understandable that in some other embodiments, the spray hole 1321 may not be limited to one, and it may also be multiple. In some embodiments, the spray head 132 and the spray rod 131 may be integrally formed, and specifically, the spray head 132 and the spray rod 131 may be integrally formed by injection molding. In some embodiments, the spray head 132 and the spray rod 131 may also be split structures, and the two may be fixed by plugging or threading.

[0031] In some embodiments, the nozzle 13 can be relatively rotatable with the core assembly 12, and can be rotatably connected with the core assembly 12, for example, it can be screwed with the connecting through hole 1211. By rotatably setting the nozzle 13, it is convenient to adjust the angle of the nozzle 13. Of course, it can be understood that in some other embodiments, the nozzle 13 and the core assembly 12 can be fixedly connected.

[0032] In some embodiments, the water inlet pipe 14 may be a hose, including a first end 141 and a second end 142. The first end 141 may be arranged opposite to the second end 142. The first end 141 of the water inlet pipe 14 may be connected to the movement assembly 12 by providing a joint, specifically, it may be connected to the power pump 121 of the movement assembly 12.

[0033] In some embodiments, a heating structure 15 is provided on the water inlet pipe 14, and the heating structure 15 can be provided between the first end 141 and the second end 142. The heating structure 15 can be sleeved on the outer periphery of the water inlet pipe 14. The heating structure 15 can be connected to a power supply structure (not shown) through the main board 122. When the heating structure 15 is powered on, it heats the water input into the water inlet pipe 14, so as to facilitate the adjustment of the temperature of the water flow sprayed from the nozzle 13. In some embodiments, the heating structure 15 can be connected to the main board 122, and it can be started or turned off by the main board 122. The connection between the heating structure 15 and the main board 122 and the control of the heating structure 15 by the main board 122 can be achieved by using existing technologies.

[0034] In some embodiments, the heating structure 15 may be a resistive heating structure, which may be at least one of an electric heating film, a heating sheet, and a heating wire. In some embodiments, the heating structure 15 may use a heating wire, which may be wound into a spiral shape. Of course, it is understandable that in some other embodiments, the heating structure 15 may not be limited to a spiral shape, and may be a columnar structure with two ends through. Specifically, the heating structure 15 may be an electric heating film or a heating sheet, which may be wound into a columnar structure and coated on the periphery of the water inlet pipe 14. In some embodiments, the heating structure 15 may also not be limited to a spiral or a columnar shape, and may be a sheet, which may be attached to the periphery of the water inlet pipe 14.

[0035] In some other embodiments, the heating structure 15 is not limited to being a resistance heating structure. In some embodiments, the heating structure 15 may be an electromagnetic heating structure. Specifically, the water inlet pipe 14 may be made of metal, and the electromagnetic heating structure may include an electromagnetic induction coil, which may be arranged on the periphery of the water inlet pipe 14 and connected to the main board 122, and may generate electromagnetic induction when powered on, and heat the water flow input therein by generating heat through the water inlet pipe 14 under the action of the electromagnetic field. The electromagnetic heating structure may adopt an existing electric heating structure, and its heating principle may refer to the existing electromagnetic heating principle.

[0036] In some embodiments, a counterweight structure 16 may be provided at one end of the water inlet pipe 14 away from the core assembly 12, and the counterweight structure 16 may be used to allow the water inlet pipe 14 to extend into the water, thereby facilitating the output of water in the water storage structure 20. Specifically, in some embodiments, the counterweight structure 16 may be provided at the second end 142 of the water inlet pipe 14.

[0037] In some embodiments, the counterweight structure 16 can be a temperature detection structure, which can not only play the role of counterweight, but also can be used to monitor the temperature of water in the water inlet pipe 14. The temperature detection structure can be connected to the main board 122, which can transmit the temperature information of the water inlet pipe 14 to the main board 122. The main board 122 can regulate the heating structure 15 according to the temperature information. For example, when the temperature of the water inlet pipe 14 is lower than the set temperature, the main board 122 can start the heating structure 15 or increase the heating gear, so that the water in the water inlet pipe 14 can be heated to the set temperature. When the temperature of the water inlet pipe 14 is higher than the set temperature, the main board 122 can control the heating structure 15 to turn off or reduce the heating gear. Through the cooperation of the temperature detection structure and the heating structure 15, the water in the water inlet pipe 14 can be kept in a certain temperature range. The set temperature can be a temperature range, such as 30 to 45°C. The connection between the temperature detection structure and the main board 122 and the principle that the main board 122 sends corresponding instructions to the heating structure 15 according to the temperature detected by the temperature detection structure can be realized by selecting conventional technology. In some embodiments, the temperature detection structure can be selected as a conventional temperature sensor.

[0038] In some other embodiments, the counterweight structure may be a conventional counterweight block or a gravity ball, and may not be limited to a temperature detection structure. In some embodiments, the temperature detection structure may be directly disposed on the side wall of the water inlet pipe 14 .

[0039] In some embodiments, the water storage structure 20 can be sleeved on the outer periphery of at least part of the oral irrigator body 10, and can be sleeved on the outer periphery of the shell 11, and the water inlet pipe 14 can be at least partially arranged in the water storage structure 20. An opening 211 is arranged at one end of the water storage structure 20, and a water storage chamber 22 can be formed inside. The opening 211 can be assembled with the shell 11, and the water storage structure 20 can be telescopically arranged with the shell 11. By telescopically arranging the water storage structure 20 with the shell 11, the capacity of the water storage chamber 22 in the water storage structure 20 can be adjusted, and it is conducive to the miniaturization design of the oral irrigator. In some embodiments, the water inlet pipe 14 can at least partially extend into the water storage chamber 22. The heating structure 15 on the water inlet pipe 14 can also heat the water in the water storage chamber 22. Specifically, it can preferentially heat the water in the water inlet pipe 14 and then heat the water in the water storage chamber 22. In some embodiments, the heating structure can also only heat the water in the water inlet pipe 14 or only heat the water in the water storage chamber 22. Specifically, in some embodiments, the inner wall of the water storage structure 20 may be provided with a slide rail for the housing 11 to slide. The housing 11 may be inserted into the water storage structure 20 from the opening 21 and inserted into the slide rail, and may slide back and forth along the direction of the slide rail, thereby realizing telescoping.

[0040] In some embodiments, the water storage structure 20 and the water flosser body 10 are detachable, which is convenient for replacing or replenishing the water in the water storage structure 20 and for cleaning the water storage structure 20 .

[0041] Of course, it can be understood that in some other embodiments, the water storage structure 20 and the shell 11 of the water flosser body 10 can also be an integrally molded structure. The water storage structure 20 can be integrally molded with the shell 11 by injection molding. A water inlet can be provided on the water storage structure 20, and a blocking structure can be provided at the water inlet. The water storage structure 20 can be replenished with water through the water inlet. The blocking structure can be opened and closed and installed at the water inlet, and is used to seal the water inlet when the water flosser is in use. When the blocking structure is pulled out from the water inlet, the water inlet can be opened, so that it is convenient to replace water or replenish water.

[0042] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention.
