Description

A kind of hand held cleaner

Technical field

The utility model relates to a kind of dust catcher, especially a kind of hand-held vacuum cleaner.

Background technique

Hand-held vacuum cleaner because its figure is small and exquisite, facilitate the carrying and use due to liked by users, work It is to generate air negative pressure in the shell of sealing using flow generator (i.e. motor is with movable vane piece high speed rotation) as principle, passes through Intake line draws dust, is separated air-flow with dust by dirt cup separator, then cleaned air is discharged from exhaust outlet.Hand-held is true Vacuum cleaner is powered usually using battery, and power is not as good as common domestic vacuum cleaners, but its is portable, is not required to external mains supply, It is thus particularly suited for lesser space cleaning, such as inside interior or keyboard, electric appliance.

Existing hand held cleaner, structure design in inlet channel it is longer, cause current rate to be lost, or be vented Airflow channel is changed in journey, causes exhaust airstream unsmooth, influences pneumatic rate；It is lower in hand-held cleaners script power In the case of, the above problem seems more prominent, is unfavorable for playing dust collection efficiency to the maximum extent.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provide it is a kind of design it is more reasonable, be conducive to improve dust suction The hand held cleaner of efficiency.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of hand held cleaner, including intake line and main body of dust collector, the main body of dust collector include dirt cup separation Left main part where device and the right main part where handle, main body are also built-in with flow generator, and the flow generator is horizontal To being set in the left main part, above or below the dirt cup separator, axis and the dirt cup separator Axis it is vertical, projection and the dirt cup separator in the horizontal direction is be overlapped completely or partially；The right main part is set There is exhaust outlet and is located on the linear type airflow channel at the flow generator rear.

Filter device is equipped between the flow generator and the exhaust outlet.

The beneficial effects of the utility model are: the structure design of the utility model can farthest shorten flow generator At a distance from dirt cup separator, shorten air stream transportation distance, current rate loss is reduced, hence into the air-flow of dirt cup separator Intensity is bigger；It can guarantee that the axis of flow generator and exhaust outlet are located on same linear type airflow channel again simultaneously, air-flow side It to not changing, is outwardly discharged conducive to air-flow, promotes pneumatic rate.The utility model has taken into account the negative pressure sucking gas of dust catcher Stream and discharge air-flow, keep the design in entire airflow circulating channel more reasonable, it is ensured that hand-held cleaners play suction to the maximum extent Dirt efficiency.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model；

Fig. 2 is the structural schematic diagram of second of embodiment of the utility model.

Specific embodiment

Referring to Fig.1, Fig. 2, hand held cleaner include intake line 1 and main body of dust collector 2, and main body of dust collector 2 includes a left side Main part 21 and right main part 22, handle 3, battery 8 etc. are located at right main part 22, and dirt cup separator 4, flow generator 5 are located at Left main part 21, flow generator 5 are horizontally set above or below dirt cup separator 4, the axis and dirt of flow generator 5 The axis of Cup separator 4 is vertical, and the projection of the two in the horizontal direction is overlapped completely or partially, and such design is so that dust catcher The vertical and lateral length of main body 2 can it is smaller, structure is more compact, compact, hold it is more portable.

In the course of work, the negative pressure that flow generator 5 generates sucks air-flow through intake line 1 entrainment of dust, in dirt Air-flow is separated with dust in Cup separator 4, and cleaned air finally is discharged from exhaust outlet 6；Intake line 1, dirt cup separator 4, gas Flow-generator 5, exhaust outlet 6 form the airflow channel inside dust catcher.

Preferably, being equipped with filter device 7 between flow generator 5 and exhaust outlet 6；It is isolated through dirt cup separator 4 Fine dust may be still mingled in air, it can be further by air filtration, convenient for discharge by filter device 7.

Since flow generator 4 and dirt cup separator 5 are respectively positioned on the same side in main body 2, air stream transportation is apart from short, significantly Reduce current rate loss, it is bigger hence into the current rate of dirt cup separator, and exhaust outlet 6 is located at flow generator 5 On the linear type airflow channel at rear, then the direction of exhaust airstream does not change, and further avoids power loss, for originally The lower hand held cleaner of power reduces power loss and improves dust collection efficiency, is converted into existing power utmostly Effective power；The utility model has taken into account the negative pressure suction airflow and discharge air-flow of dust catcher, makes entire airflow circulating channel It designs more reasonable, improves pneumatic rate, it is ensured that hand-held cleaners play dust collection efficiency to the maximum extent.
