Abstract
The utility model comprises a motor, a power supply terminal, a lead, a stator, an outer frame of the stator, a power supply terminal cover and an impeller. Pluralities of grooves are arranged on the contact surface between the upper cover and the lower cover of the power supply terminal to seal the power supply terminal cover. Because airflow with moisture and dust can not enter the internal via a lead groove, the water proof degree and dust resisting grade and the service life are increased, and the market prospect is wide.
Description
Technical field
The utility model relates to axial-flow blower, relates in particular to a kind of terminal cap with axial-flow blower of good water proof and dust proof performance.
Background technique
Axial-flow blower is used for needs and ventilates and each occasion of cooling off, comprises every field such as PC, electric equipment and factory installation.Axial-flow blower generally includes power supply terminal; Lead-in wire; Motor; One mutliblade impeller, these blades are clocklike around the hub member setting; Rotor; Stator iron core and housing, protective housing etc.When power supply terminal is connected power supply, be the motor power supply by lead-in wire.Impeller is by motor driving, and the air pressure attenuating by blade causes producing air and moves to blower fan continuously.Then, fan blade rising pressure promotes the rear of air from blower fan laterally, and the air that moves produces air-flow, and this air-flow plays and ventilates and cooling action.
Obviously, the air quantity of this air-flow is big more, and the heat dissipation potential of blower fan is also high more.This is because the thermal capacitance of air is certain, bigger air quantity, and just more air can be taken away more heat in the unit time.
Yet air-flow is when taking away heat, and itself is also carrying steam and dust.If these steam and dust are invaded stator, then make its corrosion and damage easily.Therefore, weigh in the technical order of a blower fan at all, the water proof and dust proof grade is an important index.
The power supply terminal of existing blower fan is arranged on the stator housing, to connect external power supply.The suitable electrification district by wire connecting portion of air-flow portability steam that blade rotation produced and dust invades inner stator, makes the winding corrosion and the damage easily of stator also to have caused the dangerous of electricity consumption.
Therefore, exist a kind of demand in the industry: the terminal cap to the power supply electrification district of axial-flow blower makes improvements, with lift shaft flow fan water proof and dust proof grade.
The model utility content
The utility model provides a kind of axial-flow blower with excellent waterproof anti-dust performance, and its technological scheme that adopts is as follows:
The loam cake of the terminal cap of axial-flow blower and the surface of contact of lower cover are provided with a plurality of grooves, and it is tightr to make that loam cake contacts with lower cover, and the induction zone that makes air-flow be difficult to the wire connecting portion by terminal enters blower fan inside, and the water proof and dust proof grade improves.
The utility model has the advantages that:, improved the water proof and dust proof grade of axial-flow blower by on the surface of contact of upper terminal lid and lower terminal lid, groove being set.
Description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by detailed description to embodiment of the present utility model.
Fig. 1 is the schematic representation of axial-flow blower power supply terminal;
Fig. 2 is the power supply terminal lid schematic representation of prior art;
Fig. 3 is an embodiment's of the utility model power supply terminal lid schematic representation
Fig. 4 is the utility model Fig. 3 power supply terminal lid embodiment's a upper terminal lid schematic representation.
Embodiment
In order further to understand feature of the present utility model, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to the usefulness of explanation, be not to be used for protection domain of the present utility model is limited.
As shown in Figure 1, be the schematic representation of axial-flow blower power supply terminal.101 is the stator housing; Power supply terminal 102 is drawn by stator interior, and at its outer installment upper terminal lid 103 and lower terminal lid 104, covers the electrification district of power supply terminal 102.
We describe the mechanism that upper terminal lid 103 and lower terminal are covered 104 parts in detail now, ask for an interview Fig. 2, are the power supply terminal lid schematic representation of prior art.202 is power supply terminal, and upper terminal lid 203 and 204 cooperations by screw 205 and screw 206 of lower terminal lid lump together.Surface of contact between the edge 207 of the edge of upper terminal lid 203 and lower terminal lid 204 is not done special processing or special the setting, unavoidably can there be the slit between the two, steam and dust can be invaded the stator interior winding at an easy rate by the slit, cause the dangerous of electricity consumption and water proof and dust proof grade to descend the working life of having reduced blower fan.
Ask for an interview Fig. 3, be the utility model power supply terminal lid schematic representation.Lower terminal lid 304 is provided with extension 308, and a plurality of tongue and groove 309a is set at the edge of lower terminal lid 304.
Ask for an interview Fig. 4, corresponding, at the edge of upper terminal lid 303 a plurality of tongue and groove 309b are set also, 309a and 309b intermesh, and make upper terminal lid 303 and 304 sealings of lower terminal lid closely, and the slit is very little.Steam and dust can't be invaded the stator interior winding by the slit, make the utility model Electrical Safety and water proof and dust proof grade improve the working life of having improved blower fan.
Should be understood that; above-mentioned detailed description to embodiment is only in order to understand the utility model; for those of ordinary skills; can be improved according to the above description or conversion; for example the tongue and groove between upper terminal lid 303 and the lower terminal lid 304 can be set to different shape; for example: trapezoidal, circular, square, so long as intermeshing, improves and conversion all should belong to the protection domain of the utility model claims tongue and groove with all that reach this purpose.
