Below with reference to Fig. 1-Figure 13, the hand held cleaner 100 according to this utility model embodiment is described.Hand held cleaner 100 can be charge type, unidirectional current class vacuum cleaner, but is not limited to this.

As it is shown in figure 1, according to the hand held cleaner 100 of this utility model embodiment, 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 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, air inlet 111 after the airflow passes dirt cup 2 entered and motor 3, flow out from blowing mouth 121.

Such as, with reference to Fig. 1 and combine Fig. 8 and Figure 10, air inlet 111 and blowing mouth 121 are formed generally as rectangular shape, air inlet 111 and blowing mouth 121 and are respectively positioned on the front end of housing 1 (such as, left end in Fig. 1), and air inlet 111 and blowing mouth 121 be spaced apart from each other setting.When motor 3 runs, negative pressure is produced in motor cavity 31, the air stream etc. making 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, its rightabout is defined as " afterwards ", the side that i.e. user of hand held 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, the blowing mouth 121 being relatively small in size by setting, air-flow from blowing mouth 121 blowout can be with certain 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, by arranging relatively large sized air inlet 111, the dust etc. blown afloat can be sucked in dirt cup 2 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, dirt cup 2 may be located on the rear side (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.It is understood that dirt cup 2 and motor 3 specifically arrange position can according to actual requirement adaptive change, this is not especially limited by this utility model.

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

Hand held cleaner 100 according to this utility model embodiment, by arranging blowing mouth 121 and making blowing mouth 121 adjacent to air inlet 111, thus is very easy to the cleaning at small gaps, and cleaning effect is good.

According to an embodiment of the present utility model, as it is shown in figure 1, blowing mouth 121 is towards the direction inclination extension of air inlet 111.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, blowing mouth 121 dust etc. blown afloat can be preferably drawn in dirt cup 2 by air inlet 111, and pick-up performance is good.

According to an embodiment of the present utility model, housing 1 is provided with blast pipe 11, and for example, referring to Fig. 1, blast pipe 11 is horizontal-extending, 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, 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, be directed away from blowing mouth 121 direction tilt 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 directly be returned 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, thus, processes simple and low cost.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 towards the oblique cambered surface etc. that the direction at housing 1 center is recessed.

According to a specific embodiment of the present utility model, air blasting passage 12 it is provided with in housing 1, one end (such as, the right-hand member in Fig. 1) of air blasting passage 12 connects 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 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 connects with motor cavity 31, blowing mouth 121 is formed at the front end of air blasting passage 12 and is positioned at the surface of air inlet 111, air blasting passage 12 extends obliquely downward on direction from back to front, now along the air flow direction flowing through air blasting passage 12, distance between air blasting passage 12 and air inlet 111 is gradually reduced, make the air-flow from blowing mouth 121 blowout can blow to the to be cleaned surface relative with air inlet 111, thus the dusts blown afloat from surface to be cleaned etc. can be inhaled in dirt cup 2 by air inlet 111 well.

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 flow to blowing mouth 121 by linear air blasting passage 12, such that it is able to the dust etc. preferably blown afloat on surface to be cleaned.Certainly, air blasting passage 12 can also extend by curve (such as, wave or camber line etc.) along the longitudinal direction.

Further, preferably edge flows through its flow direction of air-flow to air blasting passage 12, cross-sectional area is gradually reduced, as shown in figs, 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 specifically arrange position, shape, the size etc. of air blasting passage 12 specifically can be arranged according to actual requirement, preferably to meet actual requirement.

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 the way of using ultrasonic bonding, speed of welding is fast, and weld strength is high, and good airproof performance.

According to an embodiment of the present utility model, housing 1 is formed with air outlet 311.The most 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 connects 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 by motor cavity 31 and can be discharged from air outlet 311.

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

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, 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. is collected in dirt cup 2, and 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 can be made to connect with motor cavity 31, 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. blow 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, the dust-contained airflow sucked is filtered by dirt cup 2, 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 air outlet 311 can be completely enclosed, it is of course also possible to somewhat open air outlet 311, but should ensure that major part air-flow blows to blowing mouth 121.

According to an embodiment of the present utility model, blowing mouth 121 can be connected to break-make with motor cavity 31.When blowing mouth 121 connects 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 configured at conducting blowing mouth 121 and the conduction position of 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 connects with motor cavity 31, and clean air-flow can blow to surface to be cleaned by blowing mouth 121, 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 blown 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 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 be flowed out by air outlet 311；Fraction in the semiclosed air outlet of switching mechanism 4 311, i.e. motor cavity 31 can be flowed out by air outlet 311.Here, it should be noted that " semiclosed " can be understood as switching mechanism 4 encloses the part in air port 311；Or switching mechanism 4 and air outlet 311 at least part of between close together, now the most of air-flow 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 connects with motor cavity 31, 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, and push pedal 41 is formed connected entrance 411, and when switching mechanism 4 is positioned at conduction position, blowing mouth 121 is connected by connected entrance 411 with motor cavity 31.

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 the most horizontal-extending, thus push pedal 41 is the most horizontally moveable.The open rearward end of air blasting passage 12 with on motor cavity 31 for the most relative with the opening that air blasting passage 12 connects, 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 are separated by push pedal 41, thus the air-flow in motor cavity 31 will not blow out (as shown in Figure 2) by blowing mouth 121.When needing the local narrow and small structures such as keyboard are cleaned, push pedal 41 can be moved, make connected entrance 411, air blasting passage 12 open rearward end the most relative with the above-mentioned opening of motor cavity 31, thus the air-flow in motor cavity 31 can be entered into air blasting passage 12 and be blown out by blowing mouth 121 by connected entrance 411.

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 is provided with closing plate 42, closes plate 42 and extends straight down from the lower surface of push pedal 41, closes plate 42 relative with air outlet 311, closes plate 42 when switching mechanism 4 is positioned at conduction position and closes or semiclosed air outlet 311.Further, when closing plate 42 semiclosed 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, close plate 42 and be configured to bottom-up, thickness and be gradually increased, be 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, and return unit 43 is often promoting push pedal 41 on the direction of blocking position.Alternatively, return unit 43 is spring.Such as, as shown in Figures 2 and 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 in normal operating conditions.

In order to make push pedal 41 the most smoothly to move, can arrange locating dowel 421 respectively on motor 3 and closing plate 42, the two ends of spring can be respectively sleeved in the locating dowel 421 of correspondence.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 push pedal 41 movement between conduction position and blocking position by promoting push button 44.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 blowing mouth 121 and motor cavity 31 are separated by now push pedal 41, and air outlet 311 opened by closing plate 42, and push pedal 41 keeps it in this position under the elastic force effect of spring.When needing the local narrow and small structures such as keyboard are cleaned, push button 44 can be stirred forward, push pedal 41 is made to move forward, when promoting push pedal 41 to conduction position, motor cavity 31 is connected by connected entrance 411 with air blasting passage 12, and closing plate 42 moves forward to have 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, so can well small gaps be cleaned, fraction air-flow is then flowed out by air outlet 311 and the gap closed between plate 42 by air outlet 311, as shown in Figure 3.

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