Below with reference to Fig. 1-Figure 13, the hand held cleaner 100 according to the embodiment of the present invention is described.Hand held cleaner 100 can be charge type, direct current class dust catcher, but is not limited thereto.

As shown in Figure 1, according to the hand held cleaner 100 of the embodiment of the present invention, comprise housing 1, dirt cup 2 and motor 3.

Housing 1 is formed with air inlet 111 and blowing mouth 121, the contiguous air inlet 111 of blowing mouth 121 is arranged.Dirt cup 2 is located on housing 1, and dirt cup 2 is connected with air inlet 111.Motor 3 has motor cavity 31, and motor cavity 31 communicates with dirt cup 2, after the airflow passes dirt cup 2 entered and motor 3, flows out from blowing mouth 121 by air inlet 111.

Such as, with reference to Fig. 1 composition graphs 8 and Figure 10, air inlet 111 and blowing mouth 121 are formed as rectangular shape substantially, and air inlet 111 and blowing mouth 121 are all positioned at the front end of housing 1 (such as, left end in Fig. 1), the setting and air inlet 111 and blowing mouth 121 are spaced apart from each other.When motor 3 runs, negative pressure is produced in motor cavity 31, make the air stream etc. of outside dust-contained airflow such as dust-laden can enter in dirt cup 2 by air inlet 111, under the filtration of dirt cup 2, dusts in air-flow etc. are separated and are collected in dirt cup 2, and clean air-flow is then blown out by blowing mouth 121 by motor cavity 31.Here, it should be noted that, direction " front " refers to the side away from user of hand held cleaner 100, and its rightabout is defined as " afterwards ", i.e. the side of the user's handling of hand held cleaner 100.

Alternatively, blowing mouth 121 is positioned at the top of air inlet 111, but is not limited thereto.

Alternatively, the cross-sectional area of blowing mouth 121 is less than the cross-sectional area of air inlet 111.Thus, by arranging the relatively little blowing mouth of size 121, from blowing mouth 121 blow out air-flow can with certain flow rate and direction surface to be cleaned, thus effectively can blow afloat the dust etc. on surface to be cleaned, by arranging the relatively large air inlet of size 111, the dust etc. blown afloat can be sucked in dirt cup 2 as much as possible, there is good cleaning effect, and cleaning efficiency be high.

As shown in Figure 1, dirt cup 2 is positioned at the front side of motor 3.Certainly, dirt cup 2 can also be positioned at the rear side (scheming not shown) of motor 3, and now motor 3 is between air inlet 111 and dirt cup 2, thus adds the structure diversity of hand held cleaner 100.Be understandable that, the concrete setting position of dirt cup 2 and motor 3 can according to actual requirement adaptive change, the present invention does not do concrete restriction to this.

When hand held cleaner 100 carries out clean to local narrow and small structures such as such as keyboards, the air-flow blown out from blowing mouth 121 can enter into the small gaps on keyboard etc. and be blown afloat by the dust etc. of small gaps, under the effect of motor cavity 31 negative pressure, the dust blown afloat etc. can be inhaled in housing 1 by air inlet 111 and be collected in dirt cup 2.Thus, be very easy to cleaning the narrow and small structure in the places such as such as keyboard, time saving and energy saving, and cleaning effect is good.

According to the hand held cleaner 100 of the embodiment of the present invention, by arranging blowing mouth 121 and making the contiguous air inlet 111 of blowing mouth 121, thus be very easy to cleaning small gaps place, and cleaning effect is good.

According to one embodiment of present invention, as shown in Figure 1, blowing mouth 121 tilts to extend towards the direction of air inlet 111.Now the central axis of blowing mouth 121 is crossing with the central axis of air inlet 111, and intersection point is positioned at outside housing 1.Preferably, intersection point is positioned on surface (surface at the dust place on such as keyboard) to be cleaned.Thus, the dust etc. blown afloat by blowing mouth 121 can be drawn in dirt cup 2 by air inlet 111 better, and pick-up performance is good.

According to one embodiment of present invention, housing 1 is provided with blast pipe 11, for example, referring to Fig. 1, and blast pipe 11 horizontal-extending, and one end of blast pipe 11 (such as, the left end in Fig. 1, i.e. free end) stretches out outside housing 1.Wherein air inlet 111 is formed in the free end of blast pipe 11, and now air inlet 111 is positioned at the front side of blowing mouth 121.

Alternatively, the free end of blast pipe 11 end face along flow through blast pipe 11 air-flow flow direction, towards away from blowing mouth 121 direction tilt extend.Such as, as shown in Figure 1, the left end end face of blast pipe 11 in the left to right direction, be tilted to downward-extension.Thus, the air-flow blown out from blowing mouth 121 can better blow to surface to be cleaned, and is not easily directly got back in dirt cup 2 by air inlet 111.

Further, the end face of the above-mentioned free end of blast pipe 11 is formed as tapered plane, and thus, processing is simple and cost is low.Certainly, the end face of the above-mentioned free end of blast pipe 11 can also be formed as skew surface (scheming not shown), such as, is formed as the oblique cambered surface etc. recessed towards the direction at housing 1 center.

According to a specific embodiment of the present invention, air blasting passage 12 is provided with in housing 1, one end (right-hand member such as, in Fig. 1) of air blasting passage 12 is communicated with motor cavity 31 and the other end of air blasting passage 12 (left end such as, in Fig. 1) has blowing mouth 121.Thus, the air-flow in motor cavity 31 can be delivered to blowing mouth 121 by air blasting passage 12.

Such as, as shown in Figure 1, air blasting passage 12 is positioned at the top of housing 1, air blasting passage 12 extends along the longitudinal direction, the rear end of air blasting passage 12 is communicated with motor cavity 31, blowing mouth 121 is formed in the front end of air blasting passage 12 and is positioned at directly over air inlet 111, air blasting passage 12 in direction surface thereof from back to front to downward-extension, now along the air flow direction flowing through air blasting passage 12, distance between air blasting passage 12 and air inlet 111 reduces gradually, make the air-flow blown out from blowing mouth 121 can blow to the to be cleaned surface relative with air inlet 111, thus the dust etc. blown afloat from surface to be cleaned can be inhaled in dirt cup 2 by air inlet 111 well.

Alternatively, air blasting passage 12 along the longitudinal direction straight line extends, and as shown in Figure 1, thus, the air-flow in motor cavity 31 can flow to blowing mouth 121 better by linear air blasting passage 12, thus can blow afloat the dust etc. on surface to be cleaned better.Certainly, air blasting passage 12 can also extend by curve (such as, wave or camber line etc.) along the longitudinal direction.

Further, air blasting passage 12 preferably reduces gradually along the flow direction of air-flow, the cross-sectional area that flow through it, as shown in figs, thus, when airflow passes blowing mouth 121, flow velocity is improved, thus air-flow can with higher flow rate and direction surface to be cleaned, thus effectively can blow afloat the dust etc. on surface to be cleaned.

Be understandable that, the concrete setting position, shape, size etc. of air blasting passage 12 specifically can be arranged according to actual requirement, to meet actual requirement better.

Alternatively, connected by ultrasonic bonding between each pipeline of hand held cleaner 100.Wherein, each independent tubes that " each pipeline " refers on the flow direction of air-flow, air-flow passes through.Such as, the connected mode between the inlet channel 211 of the first cyclone of blast pipe 11 and dirt cup 2 is ultrasonic bonding.Thus, by adopting the mode of ultrasonic bonding, speed of welding is fast, and weld strength is high, and good airproof performance.

According to one embodiment of present invention, housing 1 is formed with air outlet 311.Such as in the example of fig. 1, air outlet 311 is positioned at the side away from air inlet 111 of motor 3, air outlet 311 is communicated with motor cavity 31, thus the dust-contained airflow entered by air inlet 111 is flowing through after dirt cup 2 filters, and clean air-flow can be discharged from air outlet 311 by motor cavity 31.

After the airflow passes dirt cup 2 entered by air inlet 111, motor 3, flow out from least one air outlet 311 and blowing mouth 121.That is, from the air-flow that air inlet 111 enters, only can flow out from air outlet 311, also can only flow out from blowing mouth 121, can also flow out from air outlet 311 and blowing mouth 121 simultaneously.Such as, after the airflow passes dirt cup 2 entered by air inlet 111 and motor 3, switchably can be flowed out from least one air outlet 311 and blowing mouth 121 by switching mechanism 4.

Such as, when hand held cleaner 100 normally works (place such as sheet, curtain etc. that clean space is larger), without the need to the dust etc. on surface to be cleaned being blown afloat by blowing mouth 121, now blowing mouth 121 can be closed, under the effect of the negative pressure of motor 3, the dusts on the surface to be cleaned sucked by air inlet 111 etc. are after dirt cup 2 filters, and dust etc. are collected in dirt cup 2, and clean air-flow then can be discharged by air outlet 311 through motor cavity 31.

When the structure that the places such as the clean such as keyboard of hand held cleaner 100 are narrow and small, blowing mouth 121 can be made to be communicated with motor cavity 31, thus the small gaps of keyboard etc. can be blowed to from the air-flow that blowing mouth 121 blows out and the dust etc. at this place is blown afloat, under the effect of motor 3 negative pressure, the dusts blown afloat etc. can be inhaled in dirt cup 2 by air inlet 111, dirt cup 2 filters the dust-contained airflow sucked, the dusts filtered out etc. are collected in dirt cup 2, and the air-flow of cleaning then flows to blowing mouth 121 to continue to blow afloat the dust on keyboard etc. through motor cavity 31.Now can be completely closed by air outlet 311, certainly, also can open air outlet 311 a little, but should ensure that most of air-flow blows to blowing mouth 121.

According to one embodiment of present invention, blowing mouth 121 can be connected to break-make with motor cavity 31.When blowing mouth 121 is communicated with motor cavity 31, the air-flow in motor cavity 31 can flow to blowing mouth 121.When blowing mouth 121 cuts off with motor cavity 31, the air-flow in motor cavity 31 can not flow to blowing mouth 121.

Such as, blowing mouth 121 can be connected to break-make by switching mechanism 4 with motor cavity 31, and switching mechanism 4 is formed at the conduction position of conducting blowing mouth 121 and motor cavity 31 and cuts off between blowing mouth 121 and the blocking position of motor cavity 31 movable.When switching mechanism 4 is positioned at conduction position, blowing mouth 121 is communicated with motor cavity 31, and clean air-flow can blow to surface to be cleaned by blowing mouth 121, and now hand held cleaner 100 can clean local narrow and small structures such as keyboards.When switching mechanism 4 is positioned at blocking position, blowing mouth 121 and motor cavity 31 cut off, and the air-flow in motor cavity 31 does not blow out by blowing mouth 121.

Further, when switching mechanism 4 is positioned at conduction position, switching mechanism 4 is closed or semiclosed air outlet 311.Switching mechanism 4 closes air outlet 311, and namely switching mechanism 4 closes air outlet 311 completely, and the air-flow in motor cavity 31 does not flow out by air outlet 311; The semiclosed air outlet 311 of switching mechanism 4, the fraction namely in motor cavity 31 can be flowed out by air outlet 311.Here, it should be noted that, " semiclosed " can be understood as the part that switching mechanism 4 closes air outlet 311; Or switching mechanism 4 and air outlet 311 at least part of between close together, the most of air-flow now in motor cavity 31 blows out from blowing mouth 121, and only fraction air-flow flows out from air outlet 311.When switching mechanism 4 is positioned at blocking position, air outlet 311 is communicated with motor cavity 31, thus when hand held cleaner 100 normally work time can treat clean surface constantly and clean.

Specifically, as shown in Figure 1-Figure 3, switching mechanism 4 comprises push pedal 41, and push pedal 41 is located on housing 1 movably, push pedal 41 is formed with connected entrance 411, and when switching mechanism 4 is positioned at conduction position, blowing mouth 121 is communicated with motor cavity 31 by connected entrance 411.

For example, referring to Fig. 1 and composition graphs 2 and Fig. 3, push pedal 41 can extend along the longitudinal direction, such as, and push pedal 41 horizontal-extending along the longitudinal direction, thus push pedal 41 can move horizontally in the longitudinal direction.The open rearward end of air blasting passage 12 with on motor cavity 31 for relative up and down with the opening that air blasting passage 12 is communicated with, now push pedal 41 is between the open rearward end and the above-mentioned opening of motor cavity 31 of air blasting passage 12.When hand held cleaner 100 normally works, switching mechanism 4 is positioned at blocking position, connected entrance 411 staggers with blowing mouth 121 and motor cavity 31, the above-mentioned opening of motor cavity 31 is closed in push pedal 41, blowing mouth 121 and motor cavity 31 separate by push pedal 41, thus the air-flow in motor cavity 31 can not be blown out (as shown in Figure 2) by blowing mouth 121.When needing to carry out clean to local narrow and small structures such as keyboards, push pedal 41 can be moved, make the open rearward end of connected entrance 411, air blasting passage 12 relative up and down with the above-mentioned opening of motor cavity 31, thus the air-flow in motor cavity 31 can enter into air blasting passage 12 by connected entrance 411 and be blown out by blowing mouth 121.

Air outlet 311 to be formed on motor cavity 31 and to be positioned at the below of push pedal 41.As shown in Figures 2 and 3, push pedal 41 is provided with shut 42, and shut 42 extends straight down from the lower surface of push pedal 41, and shut 42 is relative with air outlet 311, and when switching mechanism 4 is positioned at conduction position, shut 42 is closed or semiclosed air outlet 311.Further, when shut 42 semiclosed air outlet 311, there is between shut 42 and air outlet 311 part that gap or shut 42 close air outlet 311.Thus, while guarantee airflow effects, reduce the accuracy of manufacture of shut 42, saved cost.Alternatively, shut 42 is configured to bottom-up, thickness to be increased gradually, effectively ensure that the structural strength of shut 42.

Further, switching mechanism 4 comprises further: return unit 43, and return unit 43 is located between housing 1 and push pedal 41, and return unit 43 promotes push pedal 41 normal on the direction of blocking position.Alternatively, return unit 43 is spring.Such as, as shown in Figures 2 and 3, spring to be located between motor 3 and shut 42 and to be positioned at the front side of shut 42, and spring often promotes shut 42 backward, often remains on to make push pedal 41 blocking position cutting off blowing mouth 121 and motor cavity 31.Namely hand held cleaner 100 is often in normal operating conditions.

In order to make push pedal 41 move reposefully in the longitudinal direction, can arrange locating dowel 421 respectively on motor 3 and shut 42, the two ends of spring can be set in corresponding locating dowel 421 respectively.Alternatively, the free end of locating dowel 421 is formed as truncated cone-shaped, taper or hemispherical etc., to facilitate the installation of spring.

As shown in Figure 1-Figure 3, push pedal 41 is provided with push button 44, and push button 44 is located on the upper surface of push pedal 41, and push button 44 exposes the upper surface of housing 1.Thus, user can realize the movement of push pedal 41 between conduction position and blocking position by promoting push button 44.Alternatively, push button 44 is hollow structure, to save material, reduces costs.

Hand held cleaner 100 is in the blocking position shown in Fig. 2 under normal conditions, and blowing mouth 121 and motor cavity 31 separate by now push pedal 41, and shut 42 opens air outlet 311, and push pedal 41 makes it remain on this position under the elastic force effect of spring.When needing to carry out clean to local narrow and small structures such as keyboards, push button 44 can be stirred forward, push pedal 41 is moved forward, when promoting push pedal 41 to conduction position, motor cavity 31 is communicated with air blasting passage 12 by connected entrance 411, and shut 42 moves forward to and has certain interval with air outlet 311, thus the most of air-flow in motor cavity 31 can be blown out by blowing mouth 121 by air blasting passage 12, can clean small gaps well like this, fraction air-flow is then flowed out by the gap between air outlet 311 and shut 42 by air outlet 311, as shown in Figure 3.

Thus, by arranging switching mechanism 4, when ensureing that hand held cleaner 100 normally uses, the air-flow of discharging from air outlet 311 effectively can be utilized, and further enhancing the cleaning effect of hand held cleaner 100.

According to one embodiment of present invention, as Figure 4-Figure 7, dirt cup 2 comprises: cup, the first cyclone, whirlwind assembly and filtration members, first cyclone, whirlwind assembly and filtration members are all located in cup, first cyclone has inlet channel 211, and inlet channel 211 has air inlet 2111 and gas outlet 2112.

With reference to Fig. 5-Fig. 7, whirlwind assembly comprises multiple second cyclone 22, multiple second cyclone 22 is arranged in parallel along the circumference of the first cyclone, wherein limit guiding channel 23 between two the second cyclones 22, guiding channel 23 is communicated with gas outlet 2112 and air-flow is guided to the periphery of whirlwind assembly along the perisporium tangent line of its second adjacent cyclone 22, the the first cyclonic separation space A being suitable for air-flow being carried out to purification separation is formed between the periphery wall of whirlwind assembly and the inwall of cup, like this, to enter from inlet channel 211 when air-flow to be cleaned and tangentially guided to by guiding channel 23 in first cyclonic separation space A, can be separated for the first time air-flow, thus by particle larger in air-flow or dirt separation out and fall.Specifically, one end of inlet channel 211 is communicated with air inlet 111, the other end of inlet channel 211 is communicated with one end of guiding channel 23, the other end of guiding channel 23 is communicated with the first cyclonic separation space A, and the air-flow of being drawn by guiding channel 23 enters in the first cyclonic separation space A along the tangential direction realizing purification separation in the first cyclonic separation space A.

As shown in Figure 6, each second cyclone 22 all has bleed breach 222 and tangentially enters in the second cyclone 22 to make air-flow, guide duct 221 is provided with in each second cyclone 22, the internal perisporium of guide duct 221 and the second cyclone 22 is spaced apart from each other, guide duct 221 has wind guiding inlet 2211 and wind-guiding outlet 2212, wind guiding inlet 2211 is communicated with bleed breach 222, air-flow like this after primary separation can enter in multiple second cyclone 22 by bleed breach 222, discharged by guide duct 221 carry out further purification separation in the second cyclone 22 after.Filtration members is arranged along the outer circumferential side of whirlwind assembly, and the air-flow of whirlwind assembly periphery can be made so tangentially to be entered in the second cyclone 22 (limiting the second cyclonic separation space B in the second cyclone 22) by filtration members and bleed breach 222.Namely in the second cyclonic separation space B, further purification separation is carried out.Thus, carried out primary separation in the first cyclonic separation space A after, by the air-flow of primary purifying by entering multiple second cyclone 22 from bleed breach 222 after filtration members, to carry out purification separation again, in the second cyclonic separation space B, air-flow rotates around guide duct 221, isolated dusts etc. fall, and the air-flow again after purification enters guide duct 221 from wind guiding inlet 2211 and exports 2212 by wind-guiding discharges the second cyclone 22.

Because multiple second cyclone 22 is be arranged in parallel around the longitudinal axis circumference of the first cyclone, can be scatter by the air-flow of primary purification and enter in multiple second cyclone 22 concurrently, in multiple second cyclone 22, completing cyclonic separation respectively.

Further, egress filtering part is provided with between dirt cup 2 and motor 3.As shown in Figure 1, egress filtering part is positioned at the exit of dirt cup 2, and egress filtering part is positioned at the downstream of multiple second cyclone 22.Thus, the air-flow after multiple second cyclone 22 carries out again purification separation can be purified further by egress filtering part.Here, it should be noted that, " downstream " can be understood as the downstream of the flow direction of the air-flow flowing through dirt cup 2.

Alternatively, filtration members is HEPA (HighefficiencyparticulateairFilter, high efficiency particle air filter) part or filter cotton etc.

Thus, by adopting Cyclone Separation Technology, purification separation is carried out to the dust-contained airflow entered in dirt cup 2, and effectively can ensure the smoothness that air-flow flows in dirt cup 2, and, by arranging the first cyclone, filtration members and multiple second cyclone 22, the first cyclone and multiple second cyclone 22 is adopted to carry out secondary cyclonic separation, bulky grain in air-flow or dirt can first filter out by the first cyclone and filtration members, and the most of granule (such as dust granule) in the air-flow after primary purifying can be isolated by multiple second cyclone 22, last small part fine dust then can be filtered by egress filtering part, dirt gas good separating effect.
