For example, according to the condition of each tooth of the new user, parameters such as the time length of the corresponding tooth to be washed, the type of the used spray hole 121, the size of the washing water pressure, the washing position and the like are determined, and then the washing mode of the user is planned. In addition, the needed washing parameters corresponding to various tooth conditions can be pre-stored in the local or server, and for a new user, the corresponding washing parameters can be called according to tooth information so as to combine and plan a washing mode. And then the washing mode is stored as the washing mode corresponding to the user, so that the washing mode is called and executed in a later sequence to wash the teeth of the user, and the washing mode is directly called when the user uses the washing device conveniently in the later period.

Referring to fig. 22, fig. 22 is a schematic flow chart illustrating a control method of the multifunctional dental irrigator according to the embodiment of the present application. The control method of the multi-functional dental irrigator provided by the present embodiment is based on the control method of the multi-functional dental irrigator shown in fig. 20, and describes the process of user intervention during irrigation.

In one embodiment, the adjustment instructions include: during the execution of a flushing stage, the flushing stage is skipped and the next flushing stage is executed. That is, when the user feels that the rinsing of the corresponding tooth portion in a certain rinsing stage is not comfortable or takes too long, the user can issue the adjustment command to skip the rinsing stage or the rest of the rinsing stage and directly proceed to the next rinsing stage.

In one embodiment, a step skip key may be provided on the multi-functional irrigator 100, and the step skip key is operated to issue an adjustment command to execute the adjustment command to skip the irrigation step being executed.

In one embodiment, the adjustment instructions include: after a flush phase is performed, the flush phase continues to be performed. That is, when the user feels that the cleaning time for rinsing the corresponding tooth portion in a certain rinsing stage is too short, the user should continue to rinse the tooth. Sometimes, the adjustment command may be issued to continue the rinsing phase if the rinsing time is sensed to be too short only after the rinsing phase is completed. For example, when the current multi-functional tooth flusher 100 finishes the upper teeth gap flushing stage and the user feels that the tooth is not flushed, the user can manually select "flushing the upper teeth gap" to continue to charge the upper teeth gap flushing stage, and after the flushing is performed for a certain time, the user cancels "flushing the upper teeth gap", so that the multi-functional tooth flusher 100 continues to be connected, and the next flushing stage is performed.

In one embodiment, the adjustment instructions include: after the flushing mode is executed, a flushing stage is selected and executed. After each stage of the washing mode is executed, the user sometimes checks the washing condition of the teeth, and when a certain tooth is found to be not washed completely or needs to be washed again, the user can send the adjustment instruction to select the corresponding washing stage, and the washing stage is executed again to wash the tooth.

in step S461, a flush stage corresponding to the execution of the adjustment command is added to the flush mode.

And step S462, storing the updated flushing mode as the flushing mode corresponding to the user.

By adding the flushing stage which is correspondingly executed by the adjusting instruction in the flushing mode, the personalized needs of the user can be better adapted. And the updated flushing mode is stored as the flushing mode corresponding to the user, so that the flushing mode can be directly called when the user uses the multifunctional tooth flusher 100 next time.

In one embodiment, the adjustment instructions include: during the execution of a rinse phase, the rinse phase is extended. In step S461, the flushing stage corresponding to the execution of the adjustment command in the flushing mode is: the flush time of this flush phase of the flush mode is extended.

In one embodiment, the adjustment instructions include: during the execution of a rinsing phase, the pressure of the rinsing liquid of the rinsing phase is adjusted. In step S461, the flushing stage corresponding to the execution of the adjustment command in the flushing mode is: the pressure of the flushing liquid is increased during this flushing phase.

In one embodiment, the adjustment instructions include: during a flushing phase, the nozzles 121 on the nozzle 10 are switched. In step S461, the flushing stage corresponding to the execution of the adjustment command in the flushing mode is: in this flushing stage, the corresponding nozzle hole 121 is switched to discharge the flushing liquid.

and recording the execution times of the flushing stage corresponding to the adjustment instruction, and executing the step of updating the flushing mode when the execution times reach a set threshold value.

When using the multi-functional dental irrigator 100, the user sometimes wants to adjust the irrigation process only at a certain time of irrigation, but does not want to use the adjusted irrigation mode later, i.e., later use or before use. Thus, by recording the execution times of the flushing stage corresponding to the adjustment instruction, when the set threshold is reached, the user is considered to need to adjust the flushing mode, and the step of updating the flushing mode is executed.

Of course, it is understood that an update mode key may be provided on the multi-functional dental irrigator 100, and the step of updating the rinsing mode may be directly performed through the update mode key after the rinsing mode is completed or the instructions are adjusted.
