Problems solved by technology

[0003] Some people think of setting diode indicator lights on electric tools to indicate whether the manual tool is powered on or not by turning on and off the indicator light. However, there is usually a lot of dust in the construction site, and the surface of the tool is easily covered by stains after long-term use. The indication effect of the indicator light become worse

Embodiment

[0012] A water pump with power-on alarm function is provided with an alarm function module on the main control board of the water pump, and the alarm function module is composed of an MCU, a resistor, a diode and a BUZ.

[0013] according to figure 1 As shown, pin 7 of MCU is the control port of BUZ. After power on, the pulse voltage of pin 7 changes from low level to high level in standby, thus triggering Q201 to turn on, 5V DC voltage > BUZ > R206 > C of Q201 , e pole > ground. The power supply circuit of the BUZ is communicated, and the BUZ makes a "beep" sound when it is powered on.

[0014] Further, the MCU model is GMS87C1202.

Abstract

The invention relates to a water pump with a power-on alarm function. An alarm function module disposed on a master control board of the water pump comprises a MCU (microcontroller unit), a resistor, a diode and a BUZ (buzzer). The MCU is of GMS87C1202 type. After powered on, the water pump can give out a beep sound for reminding, an operator can hear the beep sound from afar and confirm that the water pump is powered on, and trail start of the water pump is not required.

Description

technical field [0001] The invention relates to a water pump, in particular to a water pump that emits a prompt sound after being powered on. Background technique [0002] In the field of small power tools, plug-and-play is mostly done by inserting the plug into the socket. None of the existing electric tools have a power-on prompting function. After inserting the plug into the socket, the user always needs to try turning it on in order to verify whether the power is on. [0003] Some people think of setting up a diode indicator light on the power tool to indicate whether the hand tool is powered on or not by turning on and off the indicator light, but generally there is a lot of dust in the construction site, and the surface of the tool is easily covered by stains after long-term use. The indication effect of the indicator light worse. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to propose a water pump that can send o...
