The active heat dissipation structure of the air pump motor comprises a machine head pedestal, an air pump, an air pump gland and a surface cover which are arranged orderly from bottom to top. The air pump comprises a motor and a turbine connected via a shaft, the central position of the machine head pedestal is equipped with a turbine cabin, and a turbine exhausting port is arranged below the turbine cabin; the turbine is placed in the turbine cabin, a main air flue is led out from the edge of the turbine cabin on the machine head pedestal, a secondary air flue of which the front end is enclosed is attached to the outside of the main air flue tightly, and the tail segments of the main and secondary air flues are gathered and then are extended out of the machine head pedestal. The active heat dissipation structure of the air pump motor solves the problem that the air pump enclosed in a dust absorbing and water absorbing machine is difficult for heat dissipation, drives the air to flow through the shell and interior of the air pump by utilizing a high speed air-flow pressure reduction principle to thereby achieve the active heat dissipation purpose, so that the motor works at a relative lower temperature to prolong the service life of the motor, and the motor is prevented from being burnt out due to an overhigh temperature.
Description
Technical field
The utility model relates to the dust-collecting water-absorbing machine, relates in particular to the air pump radiator structure.
Background technology
The dust-collecting water-absorbing machine is as reducing dry sound, will contain air pump, the air pump temperature raises in the time of will making work after containing air pump, cause the air pump loss fast, reduce useful life, continuous working period can not be oversize, the change possibility of air pump motor electric attribute of excess Temperature, thus increase the risk that air pump damages.Existing dust-collecting water-absorbing owner will adopt the mode of passive heat radiation that the air pump motor is dispelled the heat, this also is unfavorable for that the dust-collecting water-absorbing captain time operates, or fan is set specially the air pump motor is dispelled the heat, this has just increased the complexity of mechanism in the dust-collecting water-absorbing machine machine, and cost raises.
Summary of the invention
The deficiency that the utility model exists in order to overcome prior art provides a kind of air pump motor active heat removal structure
The utility model can be achieved by taking following technical scheme:
A kind of air pump motor active heat removal structure comprises machine head base, air pump, air pump gland and the cover from bottom to top installed successively,
Described air pump comprises motor and the turbine that links to each other with axle, and the top of motor has the motor radiating air intake,
Described machine head base centre is provided with the turbine storehouse, below, turbine storehouse has the turbine suction opeing, turbine is positioned in the turbine storehouse, on machine head base, draw main air duct from edge, turbine storehouse, be close to the inferior air channel of the arranged outside front end sealing of main air duct, the rear in primary and secondary air channel converges outside the rear pass-out machine head base with 0 ~ 60 degree angle
Described air pump gland has the hot-blast outlet that is communicated with inferior air channel front end on the machine head base, and described air pump gland middle part has the through hole that allows motor pass,
Described cover middle part has cold air inlet, and described cover is enclosed within the motor top.
Compared with prior art, the beneficial effects of the utility model are:
Motor driving turbine fan blade High Rotation Speed makes air-flow throw away at a high speed the turbine air outlet, because high velocity air is mobile, (according to Hydrodynamics Theory, flowing velocity increases, and pressure just reduces little to make the air pressure that puts on the main air duct wall be lower than atmospheric pressure; Flowing velocity reduces, pressure just increases), will produce negative pressure in the intersection in primary and secondary air channel, suction after the generation negative pressure drives air stream and enters cold air inlet, and take away the part heat that motor produces, flow out at last time air channel, converge with the air-flow of main air duct and discharge outside the machine head base, thereby make motor reach the effect of cooling.With air pump motor active heat removal structure dust-collecting water-absorbing machine temperature is reduced, make motor under relatively low temperature, work to prolong motor life, prevent from burning out motor because of excess Temperature.

Embodiment
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in detail.
Air pump motor active heat removal structure shown in Fig. 1 ~ 5 comprises machine head base 1, air pump 3, air pump gland 4, cover 5 and the top cover 6 from bottom to top installed successively.
Described cover 5 middle parts have cold air inlet 7, and described cover 5 is enclosed within motor 11 tops.
Bottom and top at turbine 13 all are lined with rubber ring 2, seal, and avoid the gas leakage situation to occur.Top cover 6 middle parts have the opening corresponding to cold air inlet 7.Arranging on the one hand of top cover 6 makes product that present embodiment is described that a preferably outward appearance be arranged, and it is easy to use to make present embodiment describe product on the other hand.
Can find out that from said structure cover 5, air pump gland 4, air pump 3 and inferior air channel 10 have consisted of the heat radiation wind path, main air duct 9 is exhaust wind paths of turbine 13, and the heat radiation wind path obtains power from main air duct 9.
We can get more information about the stream operated situation in Fig. 6, when air pump 3 running, air-flow is thrown away at a high speed turbine air outlet 14 by turbine 13, enter subsequently main air duct 9, under the effect of high velocity air, the pressure in the main air duct 9 will reduce, in main air duct, produce a subatmospheric negative pressure, and produce suction at the meet in primary and secondary air channel, air is sucked meet from inferior air channel 10, the power resources of Here it is heat radiation wind path.
As shown in Figure 6, under the effect of negative pressure, air sucks by in cover 6, air pump gland 4 and the turbine 13 formed cavitys from cold air inlet 7, after air enters cavity, portion of air enters from motor radiating entrance 12 and flow back in the cavity in motor 11 movements again, a part flows through from motor 11 case surface, and the thermal current that has absorbed motor 11 heats flows in time air channels 10 from hot-blast outlet 8, and high velocity air last and main air duct 9 converges and flows out machine head base.
The air pump motor active heat removal structure of present embodiment is that the wind path that goes out with motor radiating is scattered in several, and arrange along the tangential direction on the powerful main air road of wind-force, thereby under the negative pressure of main air road generation, strengthen the discharge of the hot blast of motor radiating, therefore reduce on year-on-year basis the motor operations temperature, prolong motor life.
The above person of thought, it only is the preferred embodiment of the utility model, when the scope that can not limit with this utility model enforcement, the content of namely generally putting down in writing according to the utility model claim and utility model specification has been done simple equivalence and has been changed and modification, all still belongs within the utility model claim institute covering scope.In addition, summary part and title only are the usefulness of auxiliary patent document search, are not the interest field that limits the utility model.
