The tooth flusher mainly cleans teeth through high-pressure water flow sprayed by the tooth flusher, and the high-pressure water flow is sprayed through the nozzle after being output by a water pump of the tooth flusher, so that the pressure of the water flow sprayed by the tooth flusher is closely related to the working performance of the tooth flusher. At present, the working performance of the tooth flusher is tested by detecting the pressure of water flow sprayed by the tooth flusher under different working modes/working gears, however, the water flow output by a water pump in the tooth flusher changes due to the received control signal and the voltage/current change when the water pump works, the water flow output by the water pump changes, and the pressure of the water flow sprayed by the tooth flusher changes accordingly. Therefore, the pressure of the water jet of the tooth flushing device, the control signal for controlling the water pump and the voltage/current of the water pump during operation are a set of related data, and the operation performance of the tooth flushing device in different operation modes/operation gears cannot be accurately and comprehensively obtained only by detecting the pressure of the water jet in the existing test mode.

For the convenience of understanding the present application, the following describes a testing device of the tooth irrigator disclosed in the present embodiment in detail.

For convenience of illustration, the pressure signals mentioned in this embodiment are all the pressure signals of the water flow sprayed onto the test fixture by the tooth irrigator to be tested, which are detected by the water pressure detection module 20, and the first pressure signal is the pressure signal of the water flow output by the water pump.

The communication module 60 is used for data communication between the control module 10 and the upper computer. The test result output by the control module 10 is transmitted to an upper computer (a computer, a tablet computer and other computing terminals) to be comprehensively arranged and analyzed through software, so that not only can the pressure signal, the corresponding relation data between the electric signal and the control signal be obtained, but also the control signal can be reversely adjusted according to the control signal, the corresponding relation data between the pressure signal and the electric signal by utilizing the comparison result between the expected pressure signal and the actual pressure signal and the comparison result between the expected electric signal and the actual electric signal, so that the actual pressure signal is gradually close to the expected pressure signal through test adjustment, and the actual electric signal is gradually close to the expected electric signal through test adjustment. The expected pressure signal and the expected electric signal are a pressure signal and an electric signal which correspond to a certain control signal theoretically; the actual pressure signal and the actual electrical signal are the pressure signal detected by the water pressure detecting module 20 and the electrical signal detected by the electrical signal detecting module 40 in the actual test.

The analog-to-digital conversion circuit 22 is configured to convert the analog pressure signal into a digital pressure signal to obtain a pressure signal, and output the pressure signal to the control module 10. The analog-to-digital conversion circuit 22 in this embodiment may be any one of the existing ADC circuits, and is not limited herein.
Since the control signal generated by the control module 10 may be a PWM signal or a signal for controlling the key switch, the water pump control module 30 in the present embodiment at least includes the following two structures for different control signals.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a water pump control module according to an embodiment, and the water pump control module 30 provided in this embodiment includes a first signal receiving unit 31 and a key switching control unit 32. The first signal receiving unit 31 is configured to receive a control signal output by the control module 10, and output the control signal to the key switching control unit 32; the key switching control unit 32 is used for responding to the control signal and controlling the working mode and/or the working gear of the tested tooth flusher to be switched.
