Particularly, described rubber membrane is arc.
Beneficial effect: compared with prior art, the utility model has the advantage of: after the energising of this device coil, produce magnetic field, iron core is attracted to do straight reciprocating motion, rubber membrane is driven by iron core and does concavo-convex motion, liquid detergent in pump head chamber can be sucked or extrude, namely this device accurately can control the injected volume of washing agent, effectively can save washing agent again, can also avoid the problem of current noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereogram of the present utility model;
Fig. 3 is that entirety of the present utility model uses structure chart;
Fig. 4 is civil power halfwave rectifier figure.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
As Figure 1-3, a kind of device that automatically can drop into liquid detergent, comprise motor casing 1, coil 2, iron core 4, spring 3, pump head chamber 6 and rubber membrane 5, its coil 2 is wound on whole motor casing 1, motor casing 1 is cylindrical, inner hollow, this motor casing 1 inside is provided with spring 3 and iron core 4, spring 3 is located at the bottom of motor casing 1 inside, spring 3 upper end is provided with iron core 4, iron core 4 is up-narrow and down-wide design, the larger cylinder of the cylinder less by top and bottom forms, (large end and small end hereinafter referred to as iron core 4), the large end of iron core 4 is connected with spring 3, small end is connected with rubber membrane 5 side, pump head chamber 6 is provided with a downward opening 10, opening 10 place establishes Packed rubber membrane 5, it is outside that rubber membrane 5 is positioned at motor casing 1, rubber membrane 5 is arc, one end, pump head chamber 6 is provided with the first check valve 7 for sucking liquid detergent, the other end is provided with the second check valve 9 for extruding liquid detergent, upper end, pump head chamber 6 cross connection one pipeline 11, this pipeline and pump head chamber 6 T-shaped, it is inner that first check valve 7 and the second check valve 9 are positioned at pipeline 11, first check valve 7 side is also provided with screen pack 8, this screen pack is used for impurity screening, it is inner that this screen pack 8 is positioned at pipeline 11.
The course of work: the civil power after leading to halfwave rectifier first to coil 2, coil 2 produces the magnetic field of rule change, iron core 4, by field drives, is subject to the attraction of rule, and the spring 3 of iron core 4 lower end provides restoring force to iron core 4, iron core 4 will do straight reciprocating motion, when iron core 4 moves reciprocatingly, rubber membrane 5 is driven by iron core 4, does concavo-convex motion, change the pressure in pump head chamber 6, make the liquid detergent of inside, pump head chamber 6 be inhaled into by the check valve 7 of both sides, pump head chamber 6 or extrude.
Particularly, when iron core 4 moves downward, order about rubber membrane 5 also downward, rubber membrane 5 is downward, and in pump head chamber 6, pressure diminishes, and in chamber, pressure diminishes, and liquid detergent enters in check valve 7 inflow pump head cavity from left side pipeline by screen pack 8; Iron core 4 moves upward, and orders about rubber membrane 5 also upwards, and upwards, in pump head chamber 6, pressure becomes large to rubber membrane 5, and in chamber, pressure becomes large, is extruded by the liquid detergent in pump head chamber from right one-way valve 7; Inner tank of washing machine is entered by pipeline; Two cycle of states, can reach the function automatically dropping into liquid detergent.
Above-mentioned linear electric motors need an electric current that iron core 4 can be made to move reciprocatingly, this electric current demand fulfillment 2 conditions:
1, size of current regularly changes, and the suction of such coil 2 also can rule change
2, the change of electric current can not be too fast, and coil 2 is equivalent to inductance, and inductance can block high frequency electric
As shown in Figure 4, coil is arranged diode by civil power halfwave rectifier.
