Description

The dust suction hair dryer

Technical field

The utility model relates to a kind of daily necessities, especially a kind of hair dryer with dust-absorbing function.

Background technology

Hair dryer is mainly used in the drying and the shaping of hair, but also can supply aspects such as laboratory, psyciotherapy room and commercial production, art designing to make the usefulness of local desiccation, heating and physiotherapy.Though the kind of hair dryer is a lot, structure is similar, generally all is made up of housing, handle, motor, fan, heating, deep bead, switch, power line etc.Hair dryer in use can carry out the process of air intake and air-out, and during energising, heating can produce heat, and the wind that fan blows out just becomes hot blast through behind the heating.Because present household electric blower function singleness can only be dried, so the energy of heating and motor generation much all has been wasted.

The utility model content

The purpose of the utility model provides a kind of dust suction hair dryer, not only has the function of common hair dryer, can also carry out dust suction, has made things convenient in the family the cleaning of indoor furniture, has practiced thrift the energy simultaneously.

The utility model solves the technical scheme that its technical problem adopted:

A kind of dust suction hair dryer comprises housing, handle and power line; Be respectively air outlet and air inlet in the front and back end of housing, the preceding middle-end in housing is provided with resistance wire, motor and impeller, on the handle below the housing, is provided with power switch; Motor one end is connected with power switch through power line, and the other end and impeller are affixed, wherein; Said handle is a hollow structure, flexibly connects a dust-collecting box in said handle bottom, between said motor that is connected with impeller and said resistance wire, establishes a telescopic baffle; One side of said telescopic baffle is fixed on the said inner walls through baffle mount; Offer a chute in the relevant position of said housing upper surface, the opposite side upper end of said telescopic baffle is provided with a switch, and said switch stretches out from said chute; Said air inlet, said telescopic baffle, said inner walls and said handle inner hollow cavity constitute the dust suction air intake passage, and said dust suction air intake passage is communicated with said dust-collecting box porch.

Above-mentioned dust suction hair dryer wherein, is provided with protective cover on said air inlet.

Above-mentioned dust suction hair dryer, wherein, said handle bottom and said dust-collecting box flexibly connect through screw thread.

Above-mentioned dust suction hair dryer, wherein, said telescopic baffle is the metal baffle that surfaces coated is covered with insulating barrier, is formed by connecting some bearing pins.

Above-mentioned dust suction hair dryer, wherein, said housing adopts engineering plastics or steel alloy molding moulding.

The utility model reasonable in design has the function of dust suction and blowing simultaneously, can practice thrift an electrical equipment spending, and is convenient and practical.

Fig. 2 is the structural representation of the telescopic baffle of the utility model dust suction hair dryer;

Fig. 3 is the housing upper surface chute of the utility model dust suction hair dryer and the structural representation that is positioned at switch wherein.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification of the utility model.

Please referring to shown in Figure 1, the utility model dust suction hair dryer comprises housing 1; Handle 2 and power line (not marking in the drawings), housing 1 adopts engineering plastics or steel alloy molding moulding, is respectively air outlet 11 and air inlet 12 in the front and back end of housing 1; Preceding middle-end in housing 1 is provided with resistance wire 3, motor 4 and impeller 5; On the handle below the housing 12, be provided with power switch 21, motor 4 one ends are connected with power switch 21 through power line, and the other end and impeller 5 are affixed.Handle 2 is a hollow structure, flexibly connects a dust-collecting box 6 in handle 2 bottoms through screw thread, between motor that is connected with impeller 54 and resistance wire 3, establishes a telescopic baffle 7.The partial enlarged drawing of telescopic baffle 7 is as shown in Figure 2; The metal baffle that telescopic baffle 7 is covered with insulating barrier, is formed by connecting some bearing pins for surfaces coated; This type metal baffle is commercially available common metal baffle, and is with low cost, and insulating barrier is made up of rubber or other insulating materials.One side of telescopic baffle 7 is fixed on housing 1 inwall through baffle mount 71.As shown in Figure 3 in addition, offer a chute 8 in the relevant position of housing 1 upper surface, the opposite side upper end of telescopic baffle 7 is provided with a switch 72, and switch 72 stretches out from chute 8.Air inlet 12, telescopic baffle 7, housing 1 inwall and handle 2 inner hollow cavitys together constitute the dust suction air intake passage, and the dust suction air intake passage is communicated with dust-collecting box 6 porch.

Further, on air inlet 12, be provided with protective cover 9, protective cover 9 can avoid getting in its air inlet zero thing under the situation of not using hair dryer.

During assembling, the impeller 5 and the motor shaft of motor 4 are worked good, utilize electric machine support (not marking in the drawings) fixed motor 4, cooperate therebetween and realize, utilize screw thread that electric machine support is fixed on the inwall of hair dryer housing 1 again with screw thread.Utilize resistance wire support (not marking in the drawings) that resistance wire 3 is arranged with the coiling form.Electric wire in the housing 1 is postponed to power switch 21, again it is drawn handle 2, power switch 21 is snap-in the cooperation with handle 2.Handle 2 can also form through whole mould processing and manufacturing with housing 1.

When using blowing function, at first the switch 72 in the chute 8 of housing 1 upper surface cuts out, this moment, telescopic baffle 7 was in contraction state; Energized then; Turn on the power switch 21 again, 5 rotations of motor 4 impeller, resistance wire 3 produces heat simultaneously; Air-flow forms warm braw through hot resistance wire 3 backs after getting into from air inlet 12, flows out from air outlet 11 at last; When using dust-absorbing function; Switch 72 in the chute 8 of housing 1 upper surface is opened; This moment, telescopic baffle 7 was in open configuration, simultaneously dust-collecting box 6 was connected with handle 2 belows, turned on the power switch 21; The object that air inlet 12 alignings is needed dust suction; The air-flow that carries dust receives stopping of telescopic baffle 7 after air inlet 12 gets into, directly from handle 2 bore passages, get in the dust-collecting box 6 of handle 2 belows, and the insulating barrier of telescopic baffle 7 surface-coated can be avoided interior metal generation superheating phenomenon.Extract power supply after using up, cover protective cover 9, regularly also need carry out cleaning in addition dust-collecting box 6.

The above is merely the utility model preferred embodiment; Be not thus the restriction the utility model claim; So the equivalent structure that all utilization the utility model specifications and diagramatic content have been done changes, and all is included in the protection domain of the utility model.
