  • Publication number: 20230202015
    Abstract: An electric hammer includes a housing, an electric motor, an output assembly, an impact assembly, a mounting shaft, a clutch assembly, and a switching assembly. The mounting shaft is rotatable about a second axis. When the electric hammer is in the drill mode, a sleeve of the output assembly rotates. When the electric hammer is in the hammer drill mode, the sleeve rotates and an impact block of the impact assembly reciprocates in the sleeve. The switching assembly is configured to switch the clutch assembly between a first state and a second state and includes a switching element. The switching element includes a forced end and a drive end, the output assembly moving along a first axis drives the forced end to move, and the drive end is configured to drive the clutch assembly to be switched to the first state.

  • Patent number: 11650251
    Abstract: Disclosed is a chip for detection of basic electric leakage on a residual current protector. Basic electric leakage can be understood as an electric leakage signal which is generated during normal operation of an electrical appliance and cannot cause a residual current protector to trip out. The chip for detection of basic electric leakage includes a peak detection circuit, a 20 ms clock generator, a 60 ms delay circuit, a 2.5 V reference voltage module, a register module, a comparator module, a counter, a digital subtractor, an analog-to-digital converter (ADC) module, a digital-to-analog converter (DAC) module, an analog adder/analog subtractor, a selection circuit, and a circuit for delayed resetting. The present disclosure can identify and eliminate a basic electric leakage signal from an input electric leakage signal, and will not affect normal operation of a load during detection, determination, storage, and output of the electric leakage signal.

  • Patent number: 11378486
    Abstract: The present invention discloses a pollutant generation system. The pollutant generation system includes a pollution source and a pollutant emitter. The pollutant emitter is connected to the pollution source. The pollution source is composed of two gases including air and methane. The flows of the gases are strictly controlled. Then, the gases enter a magnetic bead glass bottle. Due to the disturbance of magnetic beads to the flowing of the gases, the gases are sufficiently disordered, and the two gases are sufficiently mixed by using a spiral tube to generate a uniform and stable pollution source.
