For example, referring to Fig. 1 and Fig. 8 and Figure 10 is combined, air inlet 111 and blowing mouth 121 are formed generally as rectangular shape, entered Air port 111 and blowing mouth 121 are respectively positioned on the front end (for example, 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 is run, negative pressure is produced in motor cavity 31 so that the sky of outside dust-contained airflow such as dust-laden Air-flow etc. can be entered in dirt cup 2 by air inlet 111, and under the filtration of dirt cup 2, dust in air-flow etc. is separated Out and collect in dirt cup 2, clean air-flow is then blown out by motor cavity 31 by blowing mouth 121.Here, it is necessary to explanation It is that direction " preceding " refers to the side of the remote user of hand held cleaner 100, its opposite direction is defined as " rear ", i.e. hand The side that the user for holding formula dust catcher 100 grips.

Alternatively, blowing mouth 121 is located at the top of air inlet 111, but 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 setting size phase To less blowing mouth 121, the air-flow that is blown out from blowing mouth 121 can with certain flow rate and direction surface to be cleaned, so as to Effectively to blow afloat the dust on surface to be cleaned etc., by setting relatively large sized air inlet 111, the dust that will can blow afloat Deng sucking as much as possible in dirt cup 2, there is preferable cleaning effect, and cleaning efficiency height.

As shown in figure 1, dirt cup 2 is located at the front side of motor 3.Certainly, dirt cup 2 may be located on motor 3 rear side it is (not shown Go out), now motor 3 is between air inlet 111 and dirt cup 2, so as to add the structure diversity of hand held cleaner 100. It is understood that dirt cup 2 and the specific set location of motor 3 can adaptive change, the present invention be right according to actual requirement This is not especially limited.

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

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

According to one embodiment of present invention, as shown in figure 1, the direction inclination of blowing mouth 121 towards air inlet 111 is prolonged Stretch.Now the central axis of blowing mouth 121 intersects with the central axis of air inlet 111, and intersection point is located at outside housing 1.Preferably, Intersection point is located on surface (such as surface where the dust on keyboard) to be cleaned.Thus, air inlet 111 can preferably by Dust blown afloat by blowing mouth 121 etc. is drawn into dirt cup 2, and pick-up performance is good.

According to one embodiment of present invention, housing 1 is provided with blast pipe 11, horizontal for example, referring to Fig. 1, blast pipe 11 Extension, and one end (for example, 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 In the free end of blast pipe 11, now air inlet 111 is located at the front side of blowing mouth 121.

Alternatively, the end face edge of the free end of blast pipe 11 flows through the flow direction of the air-flow of blast pipe 11, is directed away from The direction of blowing mouth 121 tilts extension.For example, as shown in figure 1, the left end end face of blast pipe 11 in the left to right direction, Extend obliquely downward.Thus, the air-flow blown out from blowing mouth 121 can preferably blow to surface to be cleaned, and be not easy directly logical Air inlet 111 is crossed 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 It is low.Certainly, the end face of the above-mentioned free end of blast pipe 11 may be formed as skew surface (not shown), for example, being formed as court Oblique cambered surface recessed to the direction at the center of housing 1 etc..

According to the specific embodiment of the present invention, air blasting passage 12, one end (example of air blasting passage 12 are provided with housing 1 Such as, the right-hand member in Fig. 1) connected with motor cavity 31 and the other end of air blasting passage 12 (for example, left end in Fig. 1) have blowing Mouth 121.Thus, the air-flow in motor cavity 31 can be delivered to blowing mouth 121 by air blasting passage 12.

For example, as shown in figure 1, air blasting passage 12 is located at the top of housing 1, air blasting passage 12 extends, blown along the longitudinal direction The rear end of wind passage 12 is connected with motor cavity 31, and blowing mouth 121 is formed in the front end of air blasting passage 12 and positioned at air inlet 111 Surface, air blasting passage 12 extend obliquely downward on direction from back to front, now along the air-flow stream for flowing through air blasting passage 12 It is gradually reduced to the distance between, air blasting passage 12 and air inlet 111 so that the air-flow blown out from blowing mouth 121 can blow to The to be cleaned surface relative with air inlet 111, so that dust blown afloat from surface to be cleaned etc. can pass through air intake well Mouth 111 is inhaled into dirt cup 2.

Alternatively, the linear extension along the longitudinal direction of air blasting passage 12, as 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, so as to preferably blow afloat on surface to be cleaned Dust etc..Certainly, air blasting passage 12 curve (for example, wave or camber line etc.) can also extend along the longitudinal direction.

Further, air blasting passage 12 preferably along flow through the flow direction of its 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, so as to which air-flow can be with higher flow rate and direction Surface to be cleaned, so as to effectively blow afloat the dust on surface to be cleaned etc..

It is understood that the specific set location of air blasting passage 12, shape, size etc. can have according to actual requirement Body is set, preferably to meet actual requirement.

Alternatively, ultrasonic bonding connection is passed through between each pipeline of hand held cleaner 100.Wherein, " each pipeline " refers to Be on the flow direction of air-flow, each independent tubes that air-flow passes through.For example, 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 using the mode of ultrasonic bonding, welding Speed is fast, and weld strength is high, and good airproof performance.

According to one embodiment of present invention, formed with air outlet 311 on housing 1.Such as in the example of fig. 1, air-out Mouth 311 connects positioned at the side of the remote air inlet 111 of motor 3, air outlet 311 with motor cavity 31, so as to be entered by air inlet 111 For the dust-contained airflow entered after flowing through dirt cup 2 and being filtered, clean air-flow can be by motor cavity 31 and from the row of air outlet 311 Go out.

After the airflow passes dirt cup 2 that is entered by air inlet 111, motor 3, from air outlet 311 and blowing mouth 121 at least One outflow.That is, the air-flow entered from air inlet 111, only can flow out from air outlet 311, can also be only from blowing Mouth 121 flows out, and can also be flowed out simultaneously from air outlet 311 and blowing mouth 121.For example, the airflow passes entered by air inlet 111 After dirt cup 2 and motor 3, can be by switching mechanism 4 switchably from least one stream in air outlet 311 and blowing mouth 121 Go out.

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

When hand held cleaner 100 cleans the narrow and small structure in the place such as keyboard, blowing mouth 121 and motor can be made Chamber 31 connects, so as to the air-flow blown out from blowing mouth 121 can blow at the small gaps of keyboard etc. and by this at dust etc. Blow afloat, in the presence of the negative pressure of motor 3, dust blown afloat etc. can be inhaled into dirt cup 2 by air inlet 111, and dirt cup 2 is to inhaling The dust-contained airflow entered is filtered, and dust filtered out etc. is collected in dirt cup 2, and clean air-flow then flows through motor cavity 31 To blowing mouth 121 to continue to blow afloat the dust on keyboard etc..Air outlet 311 can now be completely enclosed, it is of course also possible to slightly Micro- opening air outlet 311, 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 with When motor cavity 31 connects, the air-flow in motor cavity 31 can flow to blowing mouth 121.When blowing mouth 121 and motor cavity 31 separate, Air-flow in motor cavity 31 can not flow to blowing mouth 121.

For example, blowing mouth 121 can be connected to break-make with motor cavity 31 by switching mechanism 4, switching mechanism 4 is constructed Into between the conduction position of conducting blowing mouth 121 and motor cavity 31 and cut-off blowing mouth 121 and the blocking position of motor cavity 31 It is movable.When switching mechanism 4 is located 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 hand held cleaner 100 can clean to the local narrow and small structure such as keyboard. When switching mechanism 4 is located at blocking position, blowing mouth 121 separates with motor cavity 31, and the air-flow in motor cavity 31 can not be by blowing Air port 121 is blown out.

Further, when switching mechanism 4 is located at conduction position, switching mechanism 4 is closed or semiclosed air outlet 311.Cut Converting mechanism 4 closes air outlet 311, i.e. switching mechanism 4 completely encloses air outlet 311, and the air-flow in motor cavity 31 can not be by going out Flow out in air port 311；The semiclosed air outlet 311 of switching mechanism 4, i.e. fraction in motor cavity 31 can pass through air outlet 311 Outflow.Here, it is necessary to which explanation, " semiclosed " can be understood as the part that switching mechanism 4 closes air outlet 311；Or cut The distance between at least part of converting mechanism 4 and air outlet 311 is relatively near, and now 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 located at blocking position, air outlet 311 and electricity Machine cavity 31 connects, and is cleaned so as to can constantly treat clean surface when 100 normal work of hand held cleaner.

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

For example, referring to Fig. 1 and Fig. 2 and Fig. 3 is combined, push pedal 41 can extend along the longitudinal direction, for example, push pedal 41 is along front and rear Direction is horizontal-extending, so as to which push pedal 41 is horizontally moveable in the longitudinal direction.The open rearward end of air blasting passage 12 and motor cavity 31 The opening for being above used to connect with air blasting passage 12 is relative up and down, and now push pedal 41 is located at the open rearward end and motor of air blasting passage 12 Between the above-mentioned opening of chamber 31.When 100 normal work of hand held cleaner, switching mechanism 4 is located 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 the He of blowing mouth 121 Motor cavity 31 separates, so as to which the air-flow in motor cavity 31 will not be blown out (as shown in Figure 2) by blowing mouth 121.When needing to key When the narrow and small structure in the place such as disk is cleaned, push pedal 41 can be moved, makes connected entrance 411, the open rearward end of air blasting passage 12 It is relative up and down with the above-mentioned opening of motor cavity 31, so as to which the air-flow in motor cavity 31 can enter blowing by connected entrance 411 Passage 12 is simultaneously blown out by blowing mouth 121.

Air outlet 311 is formed on motor cavity 31 and positioned at the lower section of push pedal 41.As shown in Figures 2 and 3, set in push pedal 41 There is closed plate 42, closed plate 42 extends straight down from the lower surface of push pedal 41, and closed plate 42 and air outlet 311 are relative, when cutting Closed plate 42 is closed or semiclosed air outlet 311 when converting mechanism 4 is located at conduction position.Further, when closed plate 42 is semiclosed There is gap or closed plate 42 to close a part for air outlet 311 during air outlet 311, between closed plate 42 and air outlet 311. Thus, while airflow effects are ensured, the accuracy of manufacture of closed plate 42 is reduced, has saved cost.Alternatively, closed plate 42 Being configured to bottom-up, thickness gradually increases, and is effectively guaranteed the structural strength of closed plate 42.

Further, switching mechanism 4 further comprises：Return unit 43, return unit 43 are located between housing 1 and push pedal 41, Return unit 43 often promotes push pedal 41 on the direction towards blocking position.Alternatively, return unit 43 is spring.For example, such as Fig. 2 and Shown in Fig. 3, spring is located between motor 3 and closed plate 42 and often promotes closed plate backward positioned at the front side of closed plate 42, spring 42, so that push pedal 41 is often maintained at the blocking position of cut-off blowing mouth 121 and motor cavity 31.I.e. hand held cleaner 100 is often located In normal operating conditions.

In order that push pedal 41 can be moved smoothly in the longitudinal direction, can be set respectively on motor 3 and closed plate 42 Locating dowel 421 is put, the both ends of spring can be respectively sleeved in corresponding locating dowel 421.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.

The blocking position shown in Fig. 2 under normal conditions of hand held cleaner 100, now push pedal 41 is by blowing mouth 121 Separated with motor cavity 31, and closed plate 42 opens air outlet 311, push pedal 41 keeps it in the position under the elastic force effect of spring Put.When needing the structure narrow and small to the place such as keyboard to clean, push button 44 can be stirred forward, makes push pedal 41 to reach Dynamic, when promoting push pedal 41 to conduction position, connected entrance 411 connects motor cavity 31 with air blasting passage 12, and closed plate 42 to Before be moved to there is certain interval with air outlet 311, so as to which most of air-flow in motor cavity 31 can pass through air blasting passage 12 Blown out by blowing mouth 121, so small gaps can be cleaned well, and fraction air-flow is then led to by air outlet 311 The outflow of the gap between air outlet 311 and closed plate 42 is crossed, as shown in Figure 3.

Thus, by setting switching mechanism 4, in the case where ensureing the normal use of hand held cleaner 100, can to from The air-flow that air outlet 311 is discharged effectively is utilized, and further enhances the cleaning effect of hand held cleaner 100.
