Close to each other, included angle A 2 diminishes, until being changed into A1 so that connecting tube 14 will be supported by suction nozzle main body 11.
Linear pattern hose 16 is arranged between connecting tube 14 and outlet portion 113, connecting tube 14 is carried out with outlet portion 113 close
Envelope connection.Suction nozzle main body 11 and the top edge of connecting tube 14 147 surround upper shed 145 jointly, positioned at the top of hose 16；Suction nozzle
The lower edge 148 of main body 11 and connecting tube 14 surrounds under shed 146 jointly, positioned at the lower section of hose 16.
As shown in Fig. 3,4 and 6, the front end outer side of hose 16 is equipped with collar 161, and hose 16 is installed in by collar 161
In the outlet portion 113 of the rear side of suction nozzle main body 11, the internal diameter of outlet portion 113 is no more than 35 millimeters, inside suction nozzle main body 11
The left and right width of cavity, is fitted close between outlet portion 113 and collar 161, and the front and rear depth of cooperation is about 30 millimeters, and
After outlet portion 113 coordinates with collar 161, outlet portion 113 keeps opposing stationary with collar 161, and such structure causes hose
16 fronts are substantially air tight.Hose 16 is integrally formed itself by flexible plastic material, will not gas leakage.The rear edge of hose 16
The direction extension of suction airflow, such as Fig. 6, the endoporus tight fit of the outer wall of the end of hose 16 and connecting tube 14 and relatively quiet
Only, will not gas leakage.
In the present embodiment, as shown in fig. 6, when cleaner suction nozzle 10 is in the free state for being not applied to external force, straight line
14 lower edge 148 of type connecting tube and 11 rear of suction nozzle main body abut so that the axis of connecting tube 14 and the included angle A 1 of suction inlet bottom surface
For predetermined angular.
When during the motion, when connecting tube 14 is subject to external force and is elevated, such as in dust suction stroke of pulling back, dust catcher is inhaled
When mouth 10 furthers at bedding surface is from distant place toward user's body, the sheet between cleaner suction nozzle 10 and user may produce
Wrinkle hinders suction nozzle to pull back, and further pulls on connecting tube 14 and may result in the noseplate 112-2 generations of suction nozzle main body 11 with sheet
The wrinkle that protuberance is formed for fulcrum along stick up clockwise from bed surface in Fig. 6 trend (connecting tube and dust suction oral area it
Between included angle A 1 have increase tendency), in this case, torsionspring 15 is compressed and produces elastic force so that rear bottom plate
The wrinkle that 112-3 is crossed on sheet is close to connecting tube 14, and suction inlet 112-1 continues to keep being bonded with bed surface, remains optimal
Pick-up performance.
Charging type vacuum cleaner suction nozzle and the adsorption capacity on surface to be cleaned are not very big.When smooth surface cleans, because inhaling
The support surface of dirt oral area 112 comes into full contact with smooth surface to be cleaned, fits closely, as user by suction nozzle from apart from oneself
When the farthest of body retracts, the angle between connecting tube and support surface becomes larger, and the elastic force of torsionspring is not enough to overcome suction
The gravity and suction of mouth, therefore, as suction nozzle is by the user's body that furthers, connecting tube leads to the axis and support table of air passage connecting portion
Angle between face can suitably become larger, and suction nozzle can also keep fitting with smooth surface to be cleaned, it is not easy to depart to be cleaned
Smooth surface.
When cleaner suction nozzle is used for bedding when fabrics soft-surface, because fabrics soft-surface has fine hair so that
There are air gap between the support surface and fabrics soft-surface of dust suction oral area 112.For the dust catcher using alternating current, these gas
Gap is insignificant, and soft-surface can tightly be adsorbed the support surface in dust suction oral area 112 by powerful suction, ensure that clean
Effect.But because the suction of charging type vacuum cleaner is natively weaker, these air gaps will significantly reduce suction nozzle main body and soft
The tightness degree of pressure release surface fitting so that the support surface of suction nozzle lower part is easier to depart from soft-surface to be cleaned.When with
Family is when promoting cleaner suction nozzle to the direction away from body on soft-surface, because the binding site of connecting tube and suction nozzle main body
Behind dust suction oral area 112, thrust can compress cleaner suction nozzle and soft-surface.As user by cleaner suction nozzle from remote
When position body from body furthers, the fabrics soft-surface of frame may corrugate after suction nozzle, cause cleaner suction nozzle
Front be upturned, connecting tube leads to the axis of air passage connecting portion with the included angle A 1 between the support surface of dust suction oral area 112
Become larger, torsionspring produce elastic force hinder A1 become larger, make great efforts A1 being maintained at initial predetermined angular, that is, allow connecting tube and
Suction nozzle main body keeps contact, so that the rear frame of suction nozzle main body crosses the wrinkle produced on fabrics soft-surface, suction nozzle master
The front bezel of body is sunk, and dust suction oral area 112 is returned to the state combined with bedding surface, the support table of 112 bottom of dust suction oral area
Face is contacted with the fine hair on bedding surface, and the fine hair in dust suction oral area 112 holds up on bedding surface, air-flow from these fine hair it
Between brought into by and by dust on fine hair inside suction nozzle.
The effect of embodiment
According to the described cleaner suction nozzle of the present embodiment and dust catcher, because being used between connecting tube and suction nozzle main body
Rotatable mode connects, and hose connection suction nozzle main body and connecting tube, carry out sealing with outlet portion by connecting tube and connect, Ji Nengyou
Effect prevents gas leakage, and the pliability of hose itself can guarantee that the flexibility relatively rotated between connecting tube and suction nozzle main body again, when making
With the cleaner suction nozzle when dust suction on smooth surface and suction nozzle are away from user's body, the folder between connecting tube and suction nozzle main body
Angle can be minimum angles, and when suction nozzle is close to user's body, the angle of connecting tube and suction nozzle main body can suitably become larger, at this time
Resilient return member will not produce excessive elastic force, and suction nozzle rear will not tilt, and suction inlet face can be kept being bonded with smooth flat.And
Compared with the sealing difficulty of large area frictional fit, the manufacturing process sealed using hose is fairly simple, is produced in batch production
When be also easy to ensure at the same time to rotate flexibility and sealing performance.
Further, because being equipped with resilient return member between connecting tube and suction nozzle main body, and the resilient return member
Abutted against respectively with connecting tube and suction nozzle main body, elastic force can be applied to suction nozzle main body, avoided because cleaner suction nozzle is to bed
