This invention discloses an automatic control method for the water pump and heating element of a garment steamer. The method controls the heating element relay to operate at a preset duty cycle until the temperature reaches a preset preheating temperature. Upon receiving a work command, the system controls the water pump to supply water at its initial setting and the heating element to heat at its initial power, then gradually increases the heating power to its maximum. The system continuously monitors the duration for which the temperature remains within the preset temperature range. If the duration does not reach the preset threshold, the heating power is reduced and the water pump supply setting is increased, and the monitoring is repeated. If the duration reaches the preset threshold multiple times consecutively, the current water pump supply setting is determined as the matching water volume setting and stored. Subsequent operations directly call upon the stored matching water volume setting to control the water pump supply. This invention effectively avoids splattering or dripping water by automatically adjusting the matching relationship between the water pump setting and the heating power, ensuring the stability of the steam temperature.

This disclosure relates to a cleaning squeegee head with integrated spray and suction, comprising a squeegee head orifice plate, a squeegee head body, and a nozzle body. The squeegee head body includes a squeegee head body and a water suction connector pipe. The squeegee head body has a flat triangular structure. The nozzle body includes a nozzle and a positioning connector. The nozzle has a slender spray nozzle at its front end and is located inside the water suction chamber. Its front end is connected to the squeegee head orifice plate. The squeegee head orifice plate blocks the front port of the water suction chamber. The cleaning surface has a spray zone in the middle and a water suction zone around it. The spray zone has slender spray holes, and the water suction zone has several suction holes distributed around the spray zone. The squeegee head body of this cleaning squeegee head has a flat triangular structure, and the water suction zone is set around the spray zone, effectively preventing water leakage or dripping. This facilitates the thin design of the squeegee head body and meets the needs of multiple usage scenarios. The suction force adsorbs and adheres the cloth to the spray zone in the middle, reliably improving the cleaning effect and further preventing water leakage or dripping. Moreover, the squeegee head does not produce dripping or residue problems when moving in the opposite direction or sideways.

This utility model relates to the field of automotive windshield wiper technology and discloses an anti-drip device for an automotive windshield wiper washer pump. It includes a washer pump and a needle valve assembly disposed at the outlet of the washer pump. The needle valve assembly includes a valve seat, a nozzle, a valve needle, and an elastic element. The valve seat has a channel with an inlet at one end communicating with the outlet of the washer pump and an outlet at the other end communicating with the nozzle. The valve needle is slidably disposed between the nozzle and the outlet. The elastic element is disposed between the valve needle and the nozzle. The valve needle has a pressure-reducing ring. With the pressure-reducing ring on the valve needle, when the spraying stops, the valve needle drives the pressure-reducing ring to slide in the opposite direction of the water flow, so that the pressure-reducing ring exerts a counteracting force on the water in the channel, thus counteracting the inertial force of the water in the channel. This prevents water from continuing to flow out of the channel and causing dripping when the washer pump stops working, thus avoiding any impact on driving safety due to dripping.
