Description

Vacuum cleaner nozzle

Background technology

Vacuum cleaner is the burnisher of using always, and its function is to suck air, and the speed of this air makes air can be mingled with dust and chip.When chip was filtered and is collected in the vacuum cleaner, air was through filtering and returning.In order to collect dust and chip, can suck air by ozzle in mode preferably.The function of the design against vacuum dust catcher of this ozzle is most important, and has developed many different models.These models are applicable to different purposes, for example on level and smooth floor, on the pile floor covering or be difficult to carry out the vacuum cleaning cleaning in the shelter that arrives and the corner.The creativeness of different product and developing market almost are difficult to estimate.

The specific question that can take place in vacuum cleaning cleaning is, loose carpet or other object can be stuck on the ozzle and with being attached on the ozzle, thus influence or can not carry out further vacuum cleaning cleaning.For fear of this problem, the valve that many vacuum cleaners dispose Electric Machine Control or can open, thus can turn air-flow down by ozzle, so that the risk minimization that stops up.The shortcoming of this method is that when airflow drops, the efficient of cleaning also can reduce.In the long run, regulating gas constantly, to flow to optimum state be unpractical.

Summary of the invention

Can solve described problem according to the present invention, thereby can maintain the higher capacity gauge of air-flow and dust, and the jammed situation of ozzle of further vacuum cleaning cleaning can not occur influencing.The present invention is based on the spontaneous reaction of people when ozzle blocks of carrying out the vacuum cleaning cleaning, promptly attempt to lift ozzle from carrying out the vacuum cleaning clean Surface.For traditional equipment, this does not have help usually, and the object meeting and the ozzle that block ozzle lift together.And be designed to according to following ozzle of the present invention: when lifting ozzle, will open a new air flue.Most of air-flow can pass through this path.Suction to the object that blocks can reduce and make this object to get loose.This process can leicht fallen D/A or is not repeatedly repeated troublesomely, so that for example also can keep carrying out in situ the vacuum cleaning cleaning to thin tablecloth.

Description of drawings

The present invention is illustrated in Fig. 1 to Fig. 5, wherein, Fig. 1 represents a kind of simple embodiment of the present invention, Fig. 2 represents a kind of than complex embodiment, Fig. 3 represents another embodiment of the invention, but Fig. 4 is the embodiment with three chosen positions, and Fig. 5 is the description more specifically of the replaceable scheme of Fig. 4.

The specific embodiment

Fig. 1 represents a kind of simple embodiment of the present invention.The ozzle 1 of vacuum cleaner is handled by handle 3, and this handle 3 constitutes suction pipes and simultaneously the air of suction is transported in the vacuum cleaner.When lifting handle 3, inlet 2 opens and most of air-flow enters vacuum cleaner by this passage now.Thereby, the suction of object is reduced and makes the ozzle mediation that becomes.The work of this device is fully intuitively.Handle 3 lifts highly more, and then the suction of vacuum cleaner is just more little.Fig. 1 a ozzle 1 under 2 closed conditions that enters the mouth when being illustrated in normal running, Fig. 1 b is illustrated in the ozzle 1 under 2 open modes that enter the mouth when lifting the position.As shown in Figure 1, the articulated section at 4 places can be made by movable part or elastomeric material (for example rubber or high molecular polymer).Articulated section 4 be designed to make last when lifting the position opened areas of inlet 2 can become suitable.

The shortcoming of the simple designs shown in Fig. 1 is that in normal running, the angle between handle/suction pipe 3 and the ozzle 1 is fixed.Fig. 2 represents a kind of more advanced design.Here, the angle between handle 3 and the ozzle is transformable, and this angle can the self-control with environment.Fig. 2 a represents normal vacuum cleaning clean conditions, and Fig. 2 b represents how air intake 2 is opened when lifting ozzle 1 by handle 3.Handle 3 is connected in ozzle by connector 4 (connecting link), and connector 4 is hollow air ducts that also constitute simultaneously between ozzle 1 and the handle 3.Connector can move around the axle at 5 places.At 6 place's tool crooked joints, and has swivel joint at 7 places.In normal use (Fig. 2 a), connector 4 be positioned at ozzle to upper/lower positions.The joint at 6 places and 7 places allows the angle between ozzle 1 and the handle 3 to change.When lifting ozzle 1 by handle 3, connector 4 is around the axle rotation at 5 places, and enters the mouth and 2 open, so that the suction effect reduces.This is illustrated among Fig. 2 b.

Fig. 3 represents the another kind of embodiment according to design of the present invention, and wherein the angle between suction pipe and the ozzle is transformable.Fig. 3 a is illustrated in the ozzle 1 of normal operating condition.Ozzle 1 is connected in handle 3 by t type pipe 8, transmits air to handle 3 in the recessed ozzle of this t type pipe and from ozzle 1.Because t type pipe 8 can rotate in the recess in the ozzle 1, and has swivel joint at 7 places, so the angle between handle 3 and the ozzle 1 is transformable.(see Fig. 3 b) when lifting by handle 3, two inlets 2 are lifted and opened to t type pipe 8 from its concave position in ozzle 1, thereby reduce suction.At the downside (invisible among the figure) of t type pipe, a pair of in addition inlet towards ozzle 1 also is opened.When lifting the position, ozzle 1 is suspended on and is linked with among 9 (strap) last, and this is linked with the reduction of entrance area and suction that 9 length is suitable for providing suitable.

When describing when of the present invention, separately be preferably with two different pieces of vacuum cleaner nozzle.A part is the part that the object of vacuum cleaning is treated in contact in the vacuum cleaning cleaning.In this article, this part is called as suction section, and has Reference numeral 13 in Fig. 1 to Fig. 5.The part of another particular importance is the part that connects vacuum cleaner nozzle and be used for the air of suction is transported to the suction pipe or the flexible pipe of vacuum cleaner.In this article, this part is called as connecting portion, and has Reference numeral 12 in Fig. 1 to Fig. 5.Between suction section and connecting portion, has the air duct that air is transported to connecting portion from suction section.When needs, in order to weaken by the air-flow of suction section and therefore to reduce the suction at the object that is cleaned by vacuum cleaning, according to the present invention, the one or more inlets or the valve that will form opening between air duct and surrounding environment are opened.By this opening, the air-flow that leads to vacuum cleaner is without suction section, therefore the airflow drops by suction section.

Essence of the present invention is the following design that is connected to of ozzle and this ozzle and handle: when lifting ozzle by handle, can form the opening that reduces suction.When ozzle lifted, this design made and subtracts suction effect intuition and generation automatically.The quantity of design in the cards is huge in the scope of the invention, and can only show a spot of example herein.

Fig. 4 represents can form a kind of design of big opening when lifting ozzle by handle.When putting down handle once more, two kinds of selections are arranged.Handle can move in one direction along the surface for the treatment of vacuum cleaning, and opening is closed fully then, and can carry out further vacuum cleaning cleaning with whole suction.Perhaps as selecting, handle can move along another direction, and dwindles opening but not exclusively close.Keep certain less opening, and carry out further vacuum cleaning cleaning with the suction that reduces.By on lift and subsequently along the whereabouts of another direction, being altered to whole suction force state is to realize easily.These three kinds of possibilities are illustrated among Fig. 4 a, Fig. 4 b and Fig. 4 c.Fig. 4 a represents normal user mode.Handle 3 is connected to and covers 10, and this lid 10 is installed to suction section 13 and provides from the suction section to the handle/passage of suction pipe 3 for air.For changing the angle between ozzle 1 and the handle 3, have crooked joint at 6 places and have swivel joint at 7 places.Fig. 4 b represents how will cover 10 when lifting by handle 3 removes from suction section 13.Therefore, form the opening 2 that reduces suction.Suction section hangs on two linking arms 11 at last, can only see in these two linking arms 11 on figure.Fig. 4 c represent by put down ozzle 1 how to make the lid under drop on the suction section, thereby keep less opening 2, can under the suction that reduces, carry out further vacuum cleaning dust suction work.When in case fall to finishing and when therefore having carried out once selecting, the mode of this selection will be kept in operation, lift again up to ozzle.When ozzle is positioned at down position, can be along different direction push-and-pull ozzles, and can not change air intake.

In Fig. 5, represent that with the form of analysing and observe different selections is arranged to simplify.Fig. 5 a represents to cover 10 and how to lean against downwards on the suction section 13, thereby does not form opening between lid 10 and suction section 13.Fig. 5 b represents to cover 10 and how to rise from suction section 13 by lifting, to form bigger opening between lid 10 and suction section 13.At this moment, suction section 13 hangs on the linking arm 11.How Fig. 5 c represents to make by decline ozzle 1 and covers 10 and finally be positioned at the position that keeps less opening.Lift vacuum cleaner nozzle by handle, this less opening can enlarge.Also can lift vacuum cleaner nozzle, make the vacuum cleaner nozzle whereabouts then and, realize closing of less opening simultaneously along the method for the treatment of vacuum cleaning clean Surface tractive on correct direction by at first utilizing handle.In Fig. 4 and design shown in Figure 5, on each side, use a linking arm 11, cover 10 to keep suction section 13 to be connected in.When lifting the position, this means that suction section is not necessarily parallel with lid last.If want to determine such collimation or other channeling direction of wanting, can use two linking arms in each side.
