As it is shown in figure 1, hand held cleaner 100 according to embodiments of the present invention, including housing 1, dirt cup 2 and motor 3.

Being formed with air inlet 111 and blowing mouth 121 on housing 1, blowing mouth 121 is arranged adjacent to air inlet 111.Dirt cup 2 sets On housing 1, dirt cup 2 is connected with air inlet 111.Motor 3 has motor cavity 31, and motor cavity 31 communicates with dirt cup 2, by air inlet After the 111 airflow passes dirt cup 2 entered and motor 3, flow out from blowing mouth 121.

For example, referring to Fig. 1 and combine Fig. 8 and Figure 10, air inlet 111 and blowing mouth 121 are formed generally as rectangular shape, enter Air port 111 and blowing mouth 121 are respectively positioned on the front end (such as, the left end in Fig. 1) of housing 1, and air inlet 111 and blowing mouth 121 Be spaced apart from each other setting.When motor 3 runs, in motor cavity 31, produce negative pressure so that the sky of outside dust-contained airflow such as dust-laden Air-flows etc. can enter in dirt cup 2 by air inlet 111, and under the filtration of dirt cup 2, the dust in air-flow etc. is separated Out and be collected in dirt cup 2, clean air-flow is then blown out by blowing mouth 121 by motor cavity 31.Here, explanation is needed Being that direction " front " refers to the side away from user of hand held cleaner 100, its rightabout is defined as " afterwards ", i.e. hands Hold the side that the user of formula vacuum cleaner 100 grips.

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

Alternatively, the cross-sectional area of blowing mouth 121 is less than the cross-sectional area of air inlet 111.Thus, by arranging size phase To less blowing mouth 121, can be with certain flow rate and direction surface to be cleaned from the air-flow of blowing mouth 121 blowout, thus can Effectively to blow afloat the dust etc. on surface to be cleaned, by arranging relatively large sized air inlet 111, the dust that can will blow afloat Suck in dirt cup 2 Deng as much as possible, there is preferable cleaning effect, and cleaning efficiency is high.

As it is shown in figure 1, dirt cup 2 is positioned at the front side of motor 3.Certainly, to may be located on the rear side of motor 3 (not shown for dirt cup 2 Go out), now motor 3 is between air inlet 111 and dirt cup 2, thus adds the structure diversity of hand held cleaner 100. It is understood that dirt cup 2 and motor 3 specifically arrange position can according to actual requirement adaptive change, the present invention couple This is not especially limited.

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

Hand held cleaner 100 according to embodiments of the present invention, by arranging blowing mouth 121 and making blowing mouth 121 neighbouring Air inlet 111, thus be very easy to the cleaning at small gaps, and cleaning effect is good.

According to one embodiment of present invention, as it is shown in figure 1, blowing mouth 121 towards air inlet 111 direction tilt prolong Stretch.Now the central axis of blowing mouth 121 intersects 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, air inlet 111 can preferably by The dust etc. blown afloat by blowing mouth 121 is drawn in dirt cup 2, 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, blast pipe 11 level Extend, and one end (such as, the left end in Fig. 1, i.e. free end) of blast pipe 11 is stretched out outside housing 1.Wherein air inlet 111 is formed At the free end of blast pipe 11, 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, be directed away from The direction of blowing mouth 121 tilts to extend.Such as, as it is shown in figure 1, the left end end face of blast pipe 11 in the left to right direction, Extend obliquely downward.Thus, can preferably blow to surface to be cleaned from the air-flow of blowing mouth 121 blowout, and be difficult to the most logical Cross air inlet 111 to return in dirt cup 2.

Further, the end face of the above-mentioned free end of blast pipe 11 is formed as tapered plane, thus, processes simple and cost Low.Certainly, the end face of the above-mentioned free end of blast pipe 11 may be formed as skew surface (not shown), such as, is formed as court To the oblique cambered surface etc. that the direction at housing 1 center is recessed.

A specific embodiment according to the present invention, is provided with air blasting passage 12 in housing 1, one end (example of air blasting passage 12 Such as, the right-hand member in Fig. 1) connect with motor cavity 31 and the other end (such as, the left end in Fig. 1) of air blasting passage 12 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 it is 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, blows The rear end of wind passage 12 connects with motor cavity 31, and blowing mouth 121 is formed at the front end of air blasting passage 12 and is positioned at air inlet 111 Surface, air blasting passage 12 extends obliquely downward on direction from back to front, now along the air-flow stream flowing through air blasting passage 12 It is gradually reduced to, distance between air blasting passage 12 and air inlet 111 so that can blow to from the air-flow of blowing mouth 121 blowout The to be cleaned surface relative with air inlet 111, thus the dust etc. blown afloat from surface to be cleaned can pass through air intake well Mouth 111 is inhaled in dirt cup 2.

Alternatively, air blasting passage 12 straight-line extension along the longitudinal direction, as it is shown in figure 1, thus, the air-flow in motor cavity 31 can Preferably to flow to blowing mouth 121 by linear air blasting passage 12, such that it is able to preferably blow afloat on surface to be cleaned Dust etc..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 along flowing through its flow direction of air-flow, cross-sectional area is gradually reduced, such as Fig. 8 and Shown in Figure 10, thus, when airflow passes blowing mouth 121, flow velocity is improved, thus air-flow can be with higher flow rate and direction Surface to be cleaned, such that it is able to effectively blow afloat the dust etc. on surface to be cleaned.

It is understood that position, shape, size etc. are specifically set can the having according to actual requirement of air blasting passage 12 Body is arranged, preferably to meet actual requirement.

Alternatively, connected by ultrasonic bonding between each pipeline of hand held cleaner 100.Wherein, " each pipeline " refers to Be on the flow direction of air-flow, each independent tubes of passing through of air-flow.Such as, blast pipe 11 and the first whirlwind of dirt cup 2 Connected mode between the inlet channel 211 of device is ultrasonic bonding.Thus, by the way of using ultrasonic bonding, welding Speed 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.The most in the example of fig. 1, air-out Mouth 311 is positioned at the side away from air inlet 111 of motor 3, and air outlet 311 connects with motor cavity 31, thus is entered by air inlet 111 The dust-contained airflow entered is flowing through after dirt cup 2 filters, and clean air-flow can be by motor cavity 31 and from air outlet 311 row Go out.

After the airflow passes dirt cup 2 that entered by air inlet 111, motor 3, from air outlet 311 and blowing mouth 121 at least One outflow.It is to say, the air-flow entered from air inlet 111, can only flow out from air outlet 311, it is also possible to only from blowing Mouth 121 flows out, it is also possible to flow out from air outlet 311 and blowing mouth 121 simultaneously.Such as, air inlet 111 airflow passes entered After dirt cup 2 and motor 3, can be flowed by switching mechanism 4 switchably at least one from air outlet 311 and blowing mouth 121 Go out.

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

When hand held cleaner 100 cleans the local narrow and small structure such as such as keyboard, blowing mouth 121 and motor can be made Chamber 31 connects, thus from the air-flow of blowing mouth 121 blowout can blow at the small gaps of keyboard etc. and by this at dust etc. Blowing afloat, under the effect of motor 3 negative pressure, the dust blown afloat etc. can be inhaled in dirt cup 2 by air inlet 111, and dirt cup 2 is to suction The dust-contained airflow entered filters, and the dust filtered out etc. is collected in dirt cup 2, and the air-flow of cleaning then flows through motor cavity 31 To blowing mouth 121 to continue to blow afloat the dust on keyboard etc..Now air outlet 311 can be completely enclosed, it is of course also possible to slightly Micro-air outlet 311 of opening, but should ensure that major part 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 with When motor cavity 31 connects, the air-flow in motor cavity 31 can flow to blowing mouth 121.When blowing mouth 121 cuts off with motor cavity 31, 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 constructed Become at conducting blowing mouth 121 and the conduction position of motor cavity 31 and cut 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 connects with motor cavity 31, and clean air-flow can be by blowing Air port 121 blows to surface to be cleaned, and now the local narrow and small structures such as keyboard can be cleaned by hand held cleaner 100. When switching mechanism 4 is positioned at blocking position, blowing mouth 121 cuts off with motor cavity 31, and the air-flow in motor cavity 31 can not be by blowing Air port 121 blows out.

Further, when switching mechanism 4 is positioned at conduction position, switching mechanism 4 is closed or semiclosed air outlet 311.Cut Converting mechanism 4 encloses air port 311, i.e. switching mechanism 4 and completely encloses air outlet 311, and the air-flow in motor cavity 31 can not pass through Air port 311 is flowed out；Fraction in the semiclosed air outlet of switching mechanism 4 311, i.e. motor cavity 31 can pass through air outlet 311 Flow out.Here, it should be noted that " semiclosed " can be understood as switching mechanism 4 encloses the part in air port 311；Or cut Converting mechanism 4 and air outlet 311 at least part of between close together, now the most of air-flow in motor cavity 31 is from blowing mouth 121 blowouts, and only fraction air-flow flows out from air outlet 311.When switching mechanism 4 is positioned at blocking position, air outlet 311 and electricity Machine cavity 31 connects, thus can be cleaned surface to be cleaned constantly when hand held cleaner 100 normally works.

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

For example, referring to Fig. 1 and combine Fig. 2 and Fig. 3, push pedal 41 can extend along the longitudinal direction, and such as, push pedal 41 is along front and back Direction is horizontal-extending, thus push pedal 41 is the most horizontally moveable.The open rearward end of air blasting passage 12 and motor cavity 31 Upper for the most relative with the opening of air blasting passage 12 connection, now push pedal 41 is positioned at open rearward end and the motor of air blasting passage 12 Between the above-mentioned opening in chamber 31.When hand held cleaner 100 normally works, switching mechanism 4 is positioned at blocking position, connected entrance 411 stagger with blowing mouth 121 and motor cavity 31, and the above-mentioned opening of motor cavity 31 is closed in push pedal 41, and push pedal 41 is by blowing mouth 121 He Motor cavity 31 separates, thus the air-flow in motor cavity 31 will not blow out (as shown in Figure 2) by blowing mouth 121.When needs are to key When the local narrow and small structure such as dish is cleaned, push pedal 41 can be moved, make connected entrance 411, the open rearward end of air blasting passage 12 The most relative with the above-mentioned opening of motor cavity 31, thus the air-flow in motor cavity 31 can enter into blowing by connected entrance 411 Passage 12 is also blown out by blowing mouth 121.

Air outlet 311 is formed on motor cavity 31 and is positioned at the lower section of push pedal 41.As shown in Figures 2 and 3, push pedal 41 sets There is closing plate 42, close plate 42 and extend straight down from the lower surface of push pedal 41, close plate 42 relative with air outlet 311, when cutting Close plate 42 when converting mechanism 4 is positioned at conduction position to close or semiclosed air outlet 311.Further, semiclosed when closing plate 42 During air outlet 311, close to there is between plate 42 and air outlet 311 gap or close plate 42 and enclose the part in air port 311. Thus, while ensureing airflow effects, reduce the accuracy of manufacture closing plate 42, saved cost.Alternatively, plate 42 is closed It is configured to bottom-up, thickness be gradually increased, is effectively guaranteed the structural strength closing plate 42.

Further, switching mechanism 4 farther includes: return unit 43, and return unit 43 is located between housing 1 and push pedal 41, Return unit 43 is often promoting push pedal 41 on the direction of blocking position.Alternatively, return unit 43 is spring.Such as, such as Fig. 2 and Shown in Fig. 3, spring is located at motor 3 and closes between plate 42 and be positioned at the front side closing plate 42, and spring the most often promotes closing plate 42, so that push pedal 41 is often maintained at partition blowing mouth 121 and the blocking position of motor cavity 31.I.e. hand held cleaner 100 is often located In normal operating conditions.

In order to make push pedal 41 the most smoothly to move, can set on motor 3 and closing plate 42 respectively Putting locating dowel 421, the two ends of spring can be respectively sleeved in the locating dowel 421 of correspondence.Alternatively, the freedom of locating dowel 421 End 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 reveals Go out the upper surface of housing 1.Thus, user can by promote push button 44 realize push pedal 41 conduction position and blocking position it Between movement.Alternatively, push button 44 is hollow structure, to save material, reduces cost.

Hand held cleaner 100 is in the blocking position shown in Fig. 2 under normal conditions, and now push pedal 41 is by blowing mouth 121 Separating with motor cavity 31, and air outlet 311 opened by closing plate 42, push pedal 41 keeps it in this position under the elastic force effect of spring Put.When needing the local narrow and small structures such as keyboard are cleaned, push button 44 can be stirred forward, make push pedal 41 to reach Dynamic, when promoting push pedal 41 to conduction position, motor cavity 31 is connected by connected entrance 411 with air blasting passage 12, and close plate 42 to Front movement is to having certain interval with air outlet 311, thus the most of air-flow in motor cavity 31 can pass through air blasting passage 12 Being blown out by blowing mouth 121, so can be cleaned small gaps well, fraction air-flow is then led to by air outlet 311 Cross air outlet 311 and the gap closed between plate 42 is flowed out, as shown in Figure 3.

Thus, by arranging switching mechanism 4, in the case of ensureing that hand held cleaner 100 normally uses, can to from The air-flow that air outlet 311 is discharged effectively utilizes, and further enhances the cleaning effect of hand held cleaner 100.
