The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
The suction nozzle of the vacuum cleaner that goes out as shown in Figure 1, it has underframe 1, and this underframe 1 comprises back underframe part 2 that has a roller 3 and the front part 4 that on pumping direction, protrudes out forward.Dust collecter 5 is installed on the front part 4 of underframe 1; It can rotate around first horizontal rotating shaft 6; Has the pump orifice 8 that limits pump orifice leading edge 7 and pump orifice back edge 7 ' on the bottom surface of dust collecter 5; The bottom rear of dust collecter 5 is equipped with a pair of support wheel 3 '; This is positioned at the left and right sides of roller 3 to support wheel 3 ', and the strong point of support wheel 3 ' is apart from the position of the pump orifice 8 that pump orifice leading edge 7 and pump orifice back edge 7 ' are limited constant (between the two vertical range H3 more than or equal to 0 smaller or equal to 0.5mm) usually.Dust collecter 5 has first stop position, has second stop position when rotating backward when rotating forward, the qualification that dust collecter 5 receives first stop position around rotating forward of first horizontal rotating shaft 6, rotating backward receives the qualification of second stop position; Dust collecter 5 also has rest position, and when being positioned at this rest position, the strong point 13 of pump orifice leading edge 7, pump orifice back edge 7 ' and roller 3 is positioned on the same plane.Suction tube connector 9 is arranged on the back underframe part 2 of underframe 1, and it can rotate around second horizontal rotating shaft 10, and the elevation of water at second horizontal rotating shaft, 10 places is higher than the elevation of water at first horizontal rotating shaft, 6 places.This moment, dust collecter 5 was in rest position, and this moment, first horizontal rotating shaft 6 and the plane at second horizontal rotating shaft, 10 places and the angle 1 between pump orifice leading edge 7 and pump orifice back edge 7 ' the formed plane were 16 °.
When suction nozzle is worked on the hard place plate; As shown in Figure 2; Whole suction nozzle is being pushed away forward, and dust collecter 5 is in first stop position, and dust collecter 5 is with respect to turning over 13 degree forward around first horizontal rotating shaft 6 when the rest position; Promptly this moment, first horizontal rotating shaft 6 and the plane at second horizontal rotating shaft, 10 places and the angle 2 between pump orifice leading edge 7 and pump orifice back edge 7 ' the formed plane were 29 °, and roller 3 plays the support ground effects.As shown in Figure 3; Whole suction nozzle is being pulled rearward; Dust collecter 5 is in second stop position; Dust collecter 5 turned round 7 ° around second horizontal rotating shaft 10 during with respect to rest position, promptly the plane at first horizontal rotating shaft 6 and second horizontal rotating shaft, 10 places and the angle 3 between pump orifice leading edge 7 and pump orifice back edge 7 ' the formed plane be 9 ° at this moment roller 3 can not play the support ground effects, also can play the effect of support a little.
Fig. 4 shows that suction nozzle of the present invention is worked and the state of whole described suction nozzle when pushing away forward on the hag blanket, the strong point 13 of roller 3, the strong point 13 ' of support wheel 3 ' all are positioned on the carpet to be cleaned.First horizontal rotating shaft 6 and second horizontal rotating shaft 10 distance L 1 in the horizontal direction is 20 ~ 79mm; Be preferably 78mm; Second horizontal rotating shaft 10 is 1.5～15mm or 31 ~ 65mm apart from the vertical range H1 of the strong point 13; Be preferably 49mm, this moment, support wheel 3 ' played the support ground effects simultaneously with roller 3.
Fig. 5 shows that suction nozzle is worked on the hag blanket and the state of whole suction nozzle when being pulled rearward; Roller 3 leaves to be cleaned; Pump orifice leading edge 7 is pasting to be cleaned all the time with the pump orifice 8 that pump orifice back edge 7 ' is limited, and a pair of support wheel 3 ' on the front part 4 of underframe 1 is positioned on to be cleaned all the time.Vertical range H2 between first horizontal rotating shaft 6 to the pump orifice leading edge 7 and pump orifice back edge 7 ' the formed plane is 1.5 ~ 34mm, preferred 26mm, and this moment, support wheel 3 ' played the support ground effects.
Fig. 6 shows suction nozzle of the present invention and is working on the hag blanket and dust collecter during in rest position; Suction tube connector 9 is around the rotation process of second horizontal rotating shaft 10; Extreme position in the process that rotates backward is that the angle 4 between the plane at the strong point 13 places of center line and pump orifice leading edge 7, pump orifice back edge 7 ' and roller 3 of suction tube connector 9 is 51 degree, and the extreme position in the rotation process is that the angle 5 between the plane at center line and the strong point 13 places of pump orifice leading edge 7, pump orifice back edge 7 ' and roller 3 of suction tube connector 9 is 81 to spend forward; In the present embodiment promptly, suction tube connector 9 is about 30 ° around the slewing area of second horizontal rotating shaft 10.
Suction nozzle of the present invention is set up support wheel through the rear end at dust collecter, and in the course of work of suction nozzle, roller and support wheel can optionally or simultaneously be played a supporting role like this.When especially suction nozzle is worked on the hag blanket, no matter still move backward forward, support wheel plays the effect of supporting ground all the time.Because the strong point of support wheel and the position of pump orifice are constant, as long as support wheel is supported on the carpet, pump orifice also just can keep being attached on the carpet constantly, thereby has guaranteed the dust collection efficiency of suction nozzle like this.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
