In the following description, in the embodiment that is represented by different diagrammatic sketch, identical label is represented identical parts.Defined in the following description parameter only is in order to help more fully to understand the present invention as detailed structure, parts and operation, is not that the parameter with these definition limits the present invention.Moreover, known function or structure are not described in detail, because they can fuzzy the present invention on unnecessary details.
Shown in Fig. 2 to 5, the exhaust apparatus that is used for vacuum cleaner according to an aspect of the present invention comprises: discharging grid 103, itself and the vacuum motor chamber (not shown) fluid communication that is arranged on main body of dust collector 101 inside.Discharging grille cover 110 is shaped to have and discharging grid 103 corresponding shapes, so that can whether flow through discharging grid 103 according to discharged air opens or closes.When the pressure from discharged air no longer existed, elastomeric element 120 made discharging grille cover 110 turn back to the closed position from open position.
Discharging grid 103 has a plurality of pores, thereby flowing through the air of pump orifice 102 of main body of dust collector 101 and the dust that carries thereof through the dust chamber, the air that dust is filtered and cleans in described dust chamber is discharged in the external environment condition by discharging grid 103.The emissions filter (not shown) is arranged between discharging grid 103 and the vacuum motor chamber.Emissions filter is supported on the discharging grid 103, and when emissions filter filtered thin dust granule, the air of cleaning can be discharged in the external environment condition.
As shown in Figure 3, discharging grille cover 110 is shaped to the corresponding shape that can cover discharging grid 103, and preferably, discharging grille cover 110 is hinged to the upside of vacuum cleaner main body 101 by hinge.Discharging grille cover 110 comprises at least one hinge hole 111, and hinge hole 111 is formed on corresponding near at least one hinged outstanding 104 the position the discharging grid 103.Can open and close discharging grille cover 110 by rotating around at least one hinge hole 111 relative discharging grid 103.
Preferably, discharging grille cover 110 comprises: give prominence to 112, it is used for contacting with elastomeric element 120, will describe in detail this point below; And air barrier plate 113, it is formed at the front portion of grille cover 110, so that discharged air stream is directed to the left side and the right side of vacuum cleaner 100 from discharging grid 103.The effect of air barrier plate 113 is left side and the right sides that discharged air are directed to the operator from the vacuum motor chamber, prevents that simultaneously air from blowing to the front of the common vacuum cleaner main body of standing 101 of operator, thereby provides convenience for the user.
For increase can with the contacted contact area of discharged air of discharging from discharging grid 103, promptly, in order to use the power that back pressure produced by discharged air, formed a plurality of spaces or gap 115, each space or gap 115 are between the adjacent a pair of rib shape of a plurality of rib shapes outstanding 114 is outstanding.When air is discharged from by space 115, can be passed to discharging grille cover 110 by the maximum, force that back pressure produced of discharged air.
Elastomeric element 120 provides and has made discharging grille cover 110 turn back to the closed position to close the elastic restoring force of discharging grid 103, and as shown in Figure 3, elastomeric element 120 is formed by leaf spring, forms described leaf spring to produce predetermined sweep.
More specifically, elastomeric element 120 is bent so that its bottom section is corresponding with near the bottom in the seat hole 130 that forms discharging grid 103, thereby can be received in the present hole 130.In a preferred example, elastomeric element 120 can be bent twice, so that have the shape that is substantially letter " J ".
Elastomeric element 120 also comprises elastic rod 121, and it protrudes upward from the bottom, so that can contact with discharging grille cover 110.A plurality of first anticreeps outstanding 122 stretch out backward so that contiguous vacuum cleaner main body 101, and second anticreep is outstanding 123, and its direction along pump orifice 102 (Fig. 2) is stretched to the front of vacuum cleaner 101.
As shown in Figure 3, elastomeric element 121 utilize with outstanding 112 corresponding ends be arranged on the inboard of discharging grille cover 110 on give prominence to and 112 contact and be meshed, and partly towards outstanding 112 bendings, so that contact with it.
First anticreep outstanding 122 is formed at the either side of elastomeric element 121, and is used to prevent elastomeric element 120 130 disengagings from the seat hole.For this reason, first anticreep outstanding 122 and elastomeric element 121 form, so that apply the inner peripheral surface that predetermined pressure pushes a hole 130 by the wall to seat hole 130.
Second anticreep outstanding 123 is set at the sidepiece of elastomeric element 121, and is relative with first anticreep outstanding 122, and extends along the direction opposite with first anticreep outstanding 122, acts on elastic force on interior week in a hole 130 so that offset first anticreep outstanding 122.
By the cooperation of first and second anticreeps outstanding 122 and 123, elastomeric element 120 has tight interference fit on the inner peripheral surface of the wall that forms seat hole 130, thereby has prevented that elastomeric element 120 from upwards shifting out a hole 130.
As a result, as shown in Figure 4, when vacuum cleaner 100 does not use, the discharging grille cover 110 of above-mentioned structure is maintained in its closed position, so that close discharging grid 103.As shown in Figure 5, when vacuum cleaner 100 is in user mode, the back pressure of the discharged air of discharging by discharging grid 103 caused upward to the effect of power under, by along upward to around hinged outstanding 104 and hinge hole 111 rotate discharging grille covers 110 to open discharging grid 103.
As shown in Figure 6, when being opened under the back pressure effect of discharging grille cover 110 in discharged air, elastomeric element 120 extruding elastic rods 121 are with distortion in the direction of arrow F.121 pairs of hinged discharging grille covers of elastic rod 110 produce restoring forces, so that make discharging grille cover 110 to initial position (Fig. 4) deflection along the direction of the arrow A indication of Fig. 6 with respect to outstanding 112.Therefore, discharging grille cover 110 is subjected to the effect of restoring force, and discharging grille cover 110 is rotated along the direction of arrow B indication.Because the back pressure by discharging grid 103 discharged air of being discharged is greater than the restoring force that elastic pressure produces of elastomeric element 120, so, discharge grille cover 110 and remain on open mode.
When vacuum cleaner 100 shut-down operations, the operation of discharging air also stops.Therefore, under the effect of the elastic restoring force of elastomeric element 130, discharging grille cover 110 rotates along the direction of the arrow B indication of Fig. 6, turns back to original position, thereby closes discharging grid 103.Because the flow velocity of discharged air little by little reduces, rather than is suddenly turn-offed, discharging grille cover 110 has the transient force that gradually changes, and therefore, discharging grille cover 110 is turned to the closed position smoothly, rather than is closed suddenly.
As a result, discharging grid 103 can not be exposed in the external environment condition under off working state, thereby when vacuum cleaner 100 is in not user mode, has prevented that external dust from entering in the main body 101 by discharging grid 103.
As described in several embodiments of the present invention, when vacuum cleaner was used, the discharging grille cover was opened from the closed position under the power effect of the back pressure of the discharged air of discharging from the discharging grid automatically.When the vacuum cleaner shut-down operation, when perhaps not using, will discharge grille cover and push back original position, and so close the discharging grid by being arranged on elastomeric element between discharging grille cover and the main body of dust collector.Therefore, can not be exposed in the external environment condition, thereby prevent that external dust enters by the discharging grid when vacuum cleaner does not use owing to discharge grid.
Previous embodiment and advantage only are examples, do not constitute the restriction to scope of the present invention.Instruction of the present invention is easy to be used for the device of other type.And the description of embodiments of the invention only is for exemplary purposes, is not the scope of restriction following claim, and after having fully understood the present invention, concerning those skilled in the art, many replacement schemes, change and variation are conspicuous.
