[0022] Example

[0023] The following are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the following embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.

[0024] Reference Manual Attached Figure 1-2A water flosser, comprising a handle assembly 1 located on one side of the water flosser body, the water flosser body comprising a water tank 4 and a base 3, the base supporting the water tank 4, an engine assembly 6 and a circuit board 7 arranged in the base 3; the engine assembly 6 is connected to the water tank 4 and the handle assembly 1 by water channels, the circuit board 7 has a pressure sensor and is arranged on the inner surface of the base 3, a button 2 is arranged on the corresponding outer surface of the base, the engine assembly 6 is provided with a drive signal determination device, the pressure sensor generates a drive signal through the deformation of the button 2, and drives the water tank and the handle assembly to discharge water after the drive signal is determined by the engine assembly. A plurality of water flosser function buttons 2 are arranged on the base 3, and different function signals are sent to the engine assembly 6 by pressing different buttons, thereby driving the water tank and the handle assembly to produce different water discharge modes.

[0025] Reference Manual Attached Figure 3 The driving signal determination device determines the button deformation signal given by the pressure sensor device within the set time. For example, if the set time is 2 seconds, the driving signal determination device sends a driving signal to drive the water tank and the handle assembly to discharge water according to the set mode when the pressure sensor device detects that the button 2 is deformed and then returns to its original state within 2 seconds. If the button is not detected to be deformed within 2 seconds or the button is deformed and has not returned to its original state, no driving signal will be generated. This can effectively avoid the gravity effect of the water droplets on the button of the water flosser causing it to deform and cause the false touch. The driving signal determination device is a main control MCU (microcontroller chip), which is respectively connected to the driving motor on the water tank and the handle assembly, the pressure sensor device (pressure detection) on the circuit board, and the display device on the outer surface of the base. The main control MCU receives the pressure signal of the pressure sensor device on the circuit board and generates a driving signal after determination to drive the water tank and the handle assembly to discharge water and display the water discharge mode on the display device on the outer surface of the base. The different water discharge modes include different gear adjustments. The display device is used to display the different gear positions.

[0026] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
