handle is fixed to the side wall of the vehicle body; an
accommodation cavity is formed in the vehicle body, and is internally provided with a
baseboard, athrough hole is formed in the
baseboard, and a reset spring is arranged in the vehicle body; a negative pressure air cylinder is arranged below the
baseboard, a liquid outlet is formed in the negative pressure air cylinder, a push rod is fixed to a
piston of the negative pressure air cylinder, and the negative pressure air cylinder is communicated with the
accommodation cavity; a vibration air cylinder is fixed into the vehicle body, and a vibration rod is fixed to the
piston of the vibration air cylinder; the fixed mechanism comprises a partition plate and a gasbag, the partition plate is fixed to the baseboard, an air outlet one-way valve and an air inlet one-way valve are fixed to the side wall of the negative pressure air cylinder, an air outlet is formed in the gasbag, and the gasbagis communicated with the air outlet end of the air outlet one-way valve; a rotary shaft is arranged at the bottom of the vehicle body, and a
cam is fixed to the rotary shaft. According to the scheme,liquid can be prevented from dripping on the bottom face.
