The flow channel 30 runs through the handle 10 and the head 20 , one end of which is communicated with the water inlet end 11 , and the other end is communicated with the flushing hole 22 . Please also refer to the embodiment shown in FIG. 3, the head 20 defines a brush surface 201 and a bottom surface 202 opposite to the brush surface 201, and the flow channel 30 is defined between the brush surface 201 and the bottom surface 202 , a plurality of bristles 21 and flushing holes 22 are arranged on the brush surface 201 , and the flushing holes 22 pass through the brush surface 201 and communicate with the internal flow channel 30 .

The ultrasonic vibration element 40 has a piezoelectric ceramic vibration plate 41 and a power supply element (not shown) electrically connected to the piezoelectric ceramic vibration plate 41 . The piezoelectric ceramic vibration plate 41 is installed in the flow channel 30 and 20 with respect to the head. Among them, the piezoelectric ceramic vibrating plate 41 mainly uses a piezoelectric ceramic vibrator to drive a vibrating plate with a firing hole on the surface, and generates a 200KHZ-300KHZ high-frequency and micro-amplitude shock wave action after being energized to differentiate the liquid surface to make it Forms a vector of water mist molecules that emit tiny particles.

The control element 50 is installed on the handle 10 and can control whether the ultrasonic oscillation element is turned on or not.

When used as a whole, the user can choose to brush teeth or have the function of irrigating teeth according to their needs; when they want to brush their teeth, the user can hold the handle 10 and bring the plurality of bristles 21 of the head 20 close to the teeth, which can be used as a general toothbrush. ; When it is intended to be used for tooth flushing, of course, the user must first connect the water inlet end 11 of the handle 10 to a water supply source (not shown in the figure), so that the water source enters the flow channel 30 through the water inlet end 11. At this time, by controlling the The assembly 50 enables the ultrasonic oscillation assembly 40 to turn on, so that the piezoelectric ceramic vibrating plate 41 generates ultrasonic frequency vibration, so that the water flow through the flushing hole 22 ejects the ultrasonic water flow to perform a tooth-washing action, and at the same time transmits the vibration of the frequency to the head. The bristles 21 on the 20 can generate ultrasonic frequency to clean the teeth and periodontal parts in the oral cavity, so as to achieve the double cleaning effect of both irrigating and brushing.

Of course, a water supply module 60 is further provided to provide water source. As shown in the second embodiment of FIG. 4 , the water supply module 60 has a water pipe 61 , a water storage bucket 62 , a pressurized pump 63 and a main body 64 , the water storage bucket 62 and the pressurized pump 63 are located in the main body 64, and the pressurized pump 63 is located in the water storage bucket 62, and the water pipe 61 is used to communicate with the water inlet end 11 of the handle 10 and The water storage bucket 62 is used to supply the water source stored in the water storage bucket 62 to the water inlet end 11 through the water pipe 61 through the pressurized pump 63 . Of course, the water supply module 60 can also be further provided with at least one control unit (not shown) for controlling whether the water supply module 60 is turned on or not, and can also control the pressure level of the pressure pump 63, so as to Adjust the water pressure and then adjust the strength of the ultrasonic water flow from the flushing hole. The control unit can be controlled by buttons or a touch screen.

Furthermore, the third embodiment of the oral cleaning device in the present invention is shown in FIG. 5, and its structural composition is substantially the same as that of the second embodiment, the only difference is that the ultrasonic oscillation component 40 in the third embodiment is disposed in the water supply mold. In the water storage bucket 62 of the group 60, the control component 50 controls the opening or not of the water supply module 60 and the ultrasonic oscillation component 40, which can also achieve the dual cleaning functions of rinsing and brushing teeth.

In addition, the fourth embodiment of the oral cleaning device in the present invention is shown in FIG. The handle 10 and the head 20 are assembled with each other in a detachable manner, and can be replaced with different types of components of the head 20 to provide different cleaning effects. In the embodiment shown in the figure, the head 20 can be replaced with a plurality of In the form of bristles 21 , or alternatively, the head 20 has only one flushing hole 22 , and the head 20 is formed into a curved structure near the flushing hole 22 , which can perform the cleaning action of flushing teeth. The main body 64 is further provided with a storage space 65 for accommodating components of the head 20 in different forms. The storage space 65 can be configured as a structure recessed into the main body 64, and can be further provided with a storage space 65.
