The invention discloses an automatic draining pump. The automatic draining pump comprises a pump body, a shell, a first active valve, a second active valve and an upper fixed cover, wherein the first active valve, the second active valve and the pump body are arranged above the interior of the shell respectively; the upper fixed cover is arranged between the first active valve and the second active valve and is positioned on the upper wall of the interior of the shell; the pump body is arranged at the lower end of the shell and is fixed by a sealing ring; an isolating film is arranged on the contact surface of a valve seat and a valve cavity on each of the first active valve and the second active valve; an isolating film is arranged on the contact surface of a pump seat and a pump cavity; the isolating films are used for isolating water from piezoelectric vibrators; two piezoelectric vibrators for a valve and piezoelectric vibrators for a pump are single-crystal piezoelectric vibrators. Equipment for acquiring, transmitting and processing a signal is not needed, so that compared with an existing draining pump, the automatic draining pump is simple in structure and lower in cost.
Description
Technical field
The present invention relates to a kind of draining pump, particularly relate to a kind of float-controlled drainage pump.
Background technique
Draining pump is widely used in every field, existing draining pump has Non-follow control and automatic control system to carry out control two kinds of modes, by the draining pump that automatic control system controls automatically, because of its need to gather, transmission and the equipment of processing signals, make its mechanism more complicated, cost is higher, and the draining pump of Non-follow control adds cost of labor, and there is the problem of terminal valve response lag.
Summary of the invention
Object of the present invention is just to provide a kind of float-controlled drainage pump to solve the problem.
In order to achieve the above object, present invention employs following technological scheme:
A kind of float-controlled drainage pump, comprise the pump housing and housing, described a kind of float-controlled drainage pump also comprises the first aggressive valve, the second aggressive valve and upper fixed cover, described first aggressive valve, described second aggressive valve and the described pump housing are all arranged on the top in described housing, fixed lid is arranged between described first aggressive valve and described second aggressive valve, and being positioned at the upper wall of described housing, the described pump housing is arranged on the lower end of described housing, is fixed by described seal ring; Said structure, need not gather, transmit and the equipment of processing signals, therefore the present invention is simpler than existing draining pump structure, cost is lower.
Particularly, described draining pump also comprises two valve piezoelectric vibrators and pump piezoelectric vibrator, two described valve piezoelectric vibrators are each passed through the two side of described first aggressive valve and described second aggressive valve, described pump piezoelectric vibrator is through the two side of the described pump housing, the two ends of described pump piezoelectric vibrator and two described valve piezoelectric vibrators are equipped with screened lead, one end of screened lead described in every bar is connected with described valve piezoelectric vibrator, and described in every bar, the other end of screened lead is positioned at the outside of described housing; It is quicker that screened lead and piezoelectric vibrator make the present invention respond relative manual drainage row.
More specifically, the valve seat in described first aggressive valve and described second aggressive valve and the surface of contact of valve pocket are equipped with isolating film, and the surface of contact of described pump seat and pump chamber is provided with isolating film; For isolated water and piezoelectric vibrator; Two described valve piezoelectric vibrators and described pump piezoelectric vibrator are monocrystalline piezoelectric oscillator.
Beneficial effect of the present invention is:
The present invention need not gather, transmit and the equipment of processing signals, therefore the present invention is simpler than existing draining pump structure, cost is lower, and the present invention controls water inlet and the outlet of draining pump automatically by screened lead and piezoelectric vibrator, the present invention is responded fast, is better than manual drainage pump.
