Description

The microminiature drainage arrangement

The utility model relates to a kind of microminiature drainage arrangement, refers to a kind of draining pump structure of making the accumulation water of separate cold machine or dehumidifier etc. especially.

General air conditioner is because the emission problem of hot gas and cooling water all can't be in indoor installation, the structure of center system or separate cold machine is used in the former capital, and the expense of the equipment of central type air conditioner and maintenance and power consumption is very expensive, non-general family can be suitable for, the structure of separate type is used in the former capital, and at present the problem of separate cold machine maximum is that the discharging of cooling water need be pulled out a very long drainpipe, the installation of this drainpipe need be made the inclined-plane and be flowed toward lower by eminence, not only to note the gradient of its draining during because of installation, thereby increasing many people perplexs for it, and the back is installed because of fault sag, and there are dirty residual thing or dust to enter or tongue green for a long time in the water pipe, cause the draining difficulty and water pipe is broken, or there is not variety of problems such as tilting to cause the ponding damage because of water pipe, though the existing on the market at present mode with siphon principle makes cooling water reach setting height and is drained, yet this kind device needs that still the drainpipe setting is had gradient, and this cooling water competence exertion draining effect that must not dry up, so still have the shortcoming of common drainpipe installing, still make present separate cold machine produce fault, cause very big puzzlement though this problem is a minor issue.

The purpose of this utility model is: a kind of microminiature drainage arrangement is provided on the basis of the defective that overcomes above-mentioned prior art, and its specific purposes are as follows:

It is little that one of purpose provides a kind of volume, and all pump configurations are shortened in the fractional motor, and it just can be installed in the drainage arrangement of air conditioner, do not increase the puzzlement of equipment cost and assembling.

Two of purpose provides the little drainage arrangement of a kind of power consumption.

Three of purpose is to make draining highly reach about 3 to 6 meters, and 10 meters far away, make its position that meets common separate type assembling fully, more be applicable to the discharge structure of dehumidifier.

The utility model provides a kind of microminiature drainage arrangement, and its structure comprises:

-shell, it is provided with holder, and this holder is provided with perforation, and the what appropriate location is provided with rectangular opening, and the conducting strip of ground terminal is passed;

-coil holder, pad and external terminal, this coil holder are frame body, and this coil holder is wound with coil, and its central shaft is provided with the slotted eye that runs through, and inserts the magnet of inducting respectively at two ends, thereafter pad and external terminal is inserted;

-input, be provided with two dividing plates to form groove the socket rubber grommet, the joint of this input can overlap the what shell and reveal what external and do not seep water;

-copper sheathing is a hollow sleeve, inserts coil tension spring in it, and its outer shroud is inserted in O shape ring;

-main shaft is provided with through hole, and control spring is inserted, the termination of this control spring can make its card end, and so as to cooperating the keying of coil tension spring control piston, this piston cooperates rubber grommet to put what hole place, do the control of check valve, water is flowed and adverse current not according to direction initialization;

-axle sleeve, it is the T font, and the upper end is that a groove is to cooperate the main shaft design, and inside grooves is inserted a rubber grommet, and the through hole of the other end is inserted in rubber grommet;

-output is provided with the hole groove, and volute spring, backflow preventing mouth plug and rubber grommet etc. are inserted, and does the control of unidirectional water inlet, relends screw thread output is spirally connected fixedly on the what shell;

Make the magnet of inducting produce magnetic force by the coil electricity of coil holder, and then make main shaft do reciprocating action and make piston cooperate coil tension spring to do the control of check valve,, make its draining by the backflow preventing mouth plug of output and the control of volute spring do water inlet.

The utility model is compared with background technology has little, the little power consumption of volume, does not increase the puzzlement of cost and assembling, makes draining highly reach about 3 to 6 meters, and 10 meters far away, and constantly taken out beneficial effects such as opening discharging.
