Problems solved by technology
[0002] The water of the high-pressure water gun is provided by the high-pressure water pump. The quality of the motor directly affects the pressure of the water gun. The frequency of use of the high-pressure water gun is very high. Frequent switching between standby and working states requires a lot of work. water gun malfunctions frequently
[0003] When the high-pressure water gun in the prior art is switched from the working state to the standby state, the electric current and speed of the electric motor will drop to zero quickly, and then the water pressure of the water pump will not only not drop, but will rise to a certain extent, resulting in the high-pressure water gun from When the standby state is switched to the working state, the motor of the high-pressure water gun needs to be started with a high load, and the starting current is large, resulting in frequent damage to the thermal protector and the pressure switch, and the life of the motor of the high-pressure water gun will be greatly shortened. A substantial increase in production costs will seriously affect the production efficiency of the enterprise

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] like figure 1 As shown, a high-pressure water gun power control device includes a three-phase socket J1 and a high-pressure water gun, and also includes a power switch J2, a start switch S1, an AC contactor, and a solid state relay J3. The three-pole plug J1 is connected to the switching power supply J2, the start The switch S1 and the electromagnetic coil of the AC contactor form a series circuit; the auxiliary contact of the AC contactor is connected in series with the output contact of the solid state relay J3 and the motor of the high-pressure water gun; the input terminal of the solid state relay J3 is connected to the 5V DC power supply , High-pressure water gun micro switch S2 forms a series circuit; in order to prevent the water gun micro switch from being stuck, the water pump is always in working condition, and a thermal protection relay and a pressure...

The invention provides a high-pressure water gun power supply control device which comprises a three-pole plug J1 and a high-pressure water gun, and is characterized by also comprising a power switch J2, a start switch S1, an alternating current contactor and a solid state relay J3; the three-pole plug J1, the power switch J2, the start switch S1 and an electromagnetic coil of the alternating current contactor form a serial loop; an auxiliary contact of the alternating current contactor is serially connected with an output contact of the solid state relay J3 and an electric motor of the high-pressure water gun; and an input end of the solid state relay J3, a 5V direct current power supply and a high-pressure water gun micro switch S1 form a serial loop. The high-pressure water gun power supply control device solves the high-load startup problem of the electric motor of the high-pressure water gun in the prior art and realizes the low-load startup of the electric motor of the high-pressure water gun, so that the service life of equipment is prolonged, and the safety of a power circuit is improved.
Description
technical field [0001] The invention relates to a high-pressure water gun power supply control device, which belongs to the field of electronic technology. Background technique [0002] The water of the high-pressure water gun is provided by the high-pressure water pump. The quality of the motor directly affects the pressure of the water gun. The frequency of use of the high-pressure water gun is very high. Frequent switching between standby and working states requires a lot of work. Water guns often malfunction. [0003] When the high-pressure water gun in the prior art is switched from the working state to the standby state, the electric current and speed of the electric motor will drop to zero quickly, and then the water pressure of the water pump will not only not drop, but will rise to a certain extent, resulting in the high-pressure water gun from When the standby state is switched to the working state, the motor of the high-pressure water gun needs to be started with...
