Referring to Figure 1 and Figure 2, the hand-held surface cleaning apparatus that each embodiment of the application provides, main body 100 are in rodlike knot Structure.With reference to Fig. 3 and Fig. 4, air-suction channel 110, dust-collecting box 120, mistake are successively arranged along air flow path in the main body 100 of club shaped structure Filter 130, flow generator 140 and exhaust outlet 150, the longitudinal axis of 130 three of air-suction channel 110, dust-collecting box 120 and filter Line is substantially parallel to each other.

With reference to Fig. 3 and Fig. 4, the work of flow generator 140 generates negative pressure and air is driven to flow to form air-flow, air-suction channel When 110 front port is close to surface to be cleaned, air-flow is by the dust on surface to be cleaned along the axial sucking air-suction channel of main body 1 110, and it is discharged into dust-collecting box 120 from air-suction channel 110, then it is sent to filter 130.When through filter 130, dust with Air-flow separation, dust are collected in dust-collecting box 120, air-flow discharge.

In order to avoid dust is directly entered filter, the hand-held that each embodiment of the application provides along the axial direction of main body Air-flow steering portion 111 is arranged in the junction of air-suction channel 110 and dust-collecting box 120 in surface cleaning apparatus.Air-flow strikes air-flow Steering can be generated behind steering portion 111, the dust inertia of bulky grain is larger, and fluid cross-section product becomes larger in dust-collecting box 120, causes Wind speed decreased, the dust of bulky grain, which is difficult with air-flow and turns to, advances, and falls in dust-collecting box 120 under after shock, thus real The first separation of existing dust.Remaining tiny dust turns to reduce filter windward back into filter 130 is arrived with air-flow The area that face is occupied by dust, reduces gas-flow resistance, improves the efficiency of blower, while the filtering for also reducing filter is negative Lotus extends service life.Arrow shows air-flow direction of travel in figure.

Air-flow steering portion 111 makes substantially 50-150 ° of angle that air-flow turns to, it is possible to understand that, which is after turning to The angle of air-flow and 100 axis of main body.After air-flow turns to, is entered in dust-collecting box 120 obliquely, isolate most dust Enter filter 130 afterwards.

In a preferred embodiment, the average runner sectional area of dust-collecting box 120 is that the average runner of air-suction channel 110 is cut 1.5 to 4 times of area make to keep suitable static pressure in dust-collecting box, and the dust of larger particles can smoothly fall, prevent by air-flow Interference.

It should be understood that air-flow steering portion 111 has the wind-guiding face of object gas flow approach axis setting.With reference to Fig. 5, work as suction When wind channel is formed by the through slot being provided in main body 100, air-flow steering portion 111 can be the cell wall of through slot end, cell wall direction Air-suction channel setting, forms wind-guiding face.Preferably, wind-guiding face at least partially arc surface, smoothly turns to air-flow, reduces air-flow Loss.Either, with reference to Fig. 6, air-flow steering portion can be plate body 112 set in addition, and plate body 112 is towards air-suction channel 110 Setting, it is hinged with main body 100, it is converted between closing and opening air-suction channel 110 by rotation.When air-flow enters, plate body 112 maintain a certain angle, make air-flow and plate body 112 that initial collision occur；With reference to Fig. 7, when no air-flow enters, plate body 112 close air-suction channel 110, prevent the dust in dust-collecting box 120 from leaking out from air-suction channel 110.In order to further ensure plate body 112 can close air-suction channel 110 when no air-flow enters, and torsion can be arranged between plate body 112 and the cell wall of air-suction channel 110 Turn spring 113, one end of torsionspring 113 is fixed or abutted with plate body 112, and the other end is fixed or abutted with main body 100.

Referring again to Fig. 6 and Fig. 7, in a preferred embodiment, air-flow steering portion 111 is the knot of above-mentioned two situations It closes, the end of air-suction channel 110 is arranged in plate body 112, and when air-flow enters, plate body 112 is supported by rotating opening air-suction channel On the cell wall for leaning against 110 end of air-suction channel, the maximum opening angle of plate body 112 is limited with this, convenient for controlling the steering of air-flow Angle.

After air-flow flows through dust-collecting box 120, filter 130 is entered, further the entrained dust of separation.Referring again to figure 3, in a preferred embodiment, filter 130 includes filter core 131 and the supporter for filter core 131 to be installed on to main body 100 132, supporter 132 defines filter core installation cavity 133, and filter core 131 is set in filter core installation cavity 133, and filter core installation cavity 133 has Open front and after-opening, open front are blocked by orifice filter 134.Air-flow successively passes through orifice filter 134, filter core 131 carries out Second and the separation of third time dust, compared to traditional dust catcher, increase the separation series of dust, have dispersed filter Filtering load, reduce gas-flow resistance.

Further, filter 130 further includes the through-hole 135 for being opened in the circumferential cavity wall of filter core installation cavity 133, through-hole 135 Open front close to filter core installation cavity 133 is arranged, and the aperture of through-hole 135 is greater than the open pore size of orifice filter 134, through-hole 135 Function as mend wind passage, when 134 windward side of orifice filter is occupied by dust large area, moreover it is possible to arrange air-flow smoothly Out, guarantee the suction force of device.

Further, as shown in figure 4, main body 100 defines flow generator installation cavity 141, flow generator 140 is set to In flow generator installation cavity 141.It should be understood that flow generator 140 generally includes impeller and motor, motor impeller Rotation generates negative pressure, by air-flow from 130 suction airflow generator installation cavity 141 of filter, and is discharged from air outlet.

In order to avoid cleaning influence of the air-flow being discharged in the process to user, exhaust outlet 150 is usually opened in air-flow The cavity wall of device installation cavity 141.That is, air-flow is axial along main body when entering flow generator installation cavity, but arranging It is the radial direction along main body 100 when out.For this purpose, the multiple air-flows of cavity wall inner surface setting in flow generator installation cavity 141 are led It to muscle 142, is particularly located at exhaust outlet 150, forms connection exhaust outlet 150 and flow generator between each air-flow guiding rib 142 The channel of installation cavity 141.

With reference to Fig. 8, in a preferred embodiment, each air-flow guiding rib 142 is arranged in parallel, with flow generator installation cavity The angle of 141 cavity wall is 30 ° to 150 °, and air-flow is along air-flow guiding rib from steady, fast in flow generator installation cavity 141 Speed discharge, linear velocity loses caused by reducing because of direction abrupt change, guarantees the efficiency of blower.More preferably, air-flow is oriented to The end of muscle 142 is equipped with arc sections 143, plays peptizaiton to air-flow, arranges air-flow uniformly between each air-flow guiding rib 142 Out.

All the embodiments in this specification are described in a progressive manner, same and similar portion between each embodiment Dividing may refer to each other, and each embodiment focuses on the differences from other embodiments.Especially for system reality For applying example, since it is substantially similar to the method embodiment, so being described relatively simple, related place is referring to embodiment of the method Part explanation.

The above description is only an example of the present application, is not intended to limit this application.For those skilled in the art For, various changes and changes are possible in this application.All any modifications made within the spirit and principles of the present application are equal Replacement, improvement etc., should be included within the scope of the claims of this application.
