Description

Vacuum cleaner nozzles and vacuum cleaners

technical field

The utility model specifically relates to a suction nozzle of a vacuum cleaner and a vacuum cleaner containing the suction nozzle of the vacuum cleaner.

Background technique

Vacuum cleaners have been widely used in ordinary households, which can easily remove dust, but the cleaning effect on hair has not been very good, because hair is easy to adhere to the surface of carpets or fabric sofas, and it is difficult for ordinary suction nozzles to suck it. Walk. Suction nozzles with rotating roller brushes have already appeared, and the rotating roller brushes contain rollers and brush filaments. During high-speed rotation, the brush filaments can take away the hair that adheres to the carpet, but most of the hair that is carried away by the brush filaments does not really enter the dust collection mechanism of the vacuum cleaner, but is wound on the roller, and because It rotates at a high speed and is tightly entangled with the roller, which is difficult to remove. After vacuuming, the user must try to clean the hair entangled on the roller brush. Therefore, the hair cleaning problem is not really solved.

The patent document WO2015035545A discloses a suction nozzle. There is a damper behind the rotating roller brush. The opening width of the damper is not less than the width of the distribution range of the brush filaments on the roller. When the damper is used, the direction of the airflow flowing through the brush filaments into the damper is the same as the extension direction of the brush filaments, so it is easier to inhale the airflow to strip the hair from the brush filaments, preventing the hair from following the brush filaments across the damper and even being entangled on the roller. Experiments have found that the hair removal effect of the suction nozzle disclosed in the patent document WO2015035545A is better than that of ordinary suction nozzles with rotating roller brushes, and the phenomenon of hair entanglement on the roller is significantly reduced. However, if the hair is tightly clamped between multiple filaments across the damper, the hair will still be entangled with the roller; When brushing the root of the wire, this will also cause the hair to not be sucked away smoothly when the brush wire passes through the damper, but to cross the damper and wrap around the roller, and as the roller brush rotates at a high speed, it becomes tighter and tighter, and it is difficult to remove in the end.

After passing through the axial flow turbine 32 , the air flows along the connecting air duct 25 to the air outlet pipe portion 24 .

The workflow of the vacuum cleaner nozzle of the present embodiment is as follows:

Connect the suction nozzle 10 of the vacuum cleaner to the air suction port of the vacuum cleaner and start the vacuum cleaner. The air suction port can be located at the end of the extension pipe of the common vacuum cleaner, can be located under the main body of the upright vacuum cleaner, or can be located at the front of the dust cup of the vehicle-mounted vacuum cleaner. The air suction port can be directly communicated with the suction nozzle 10 of the vacuum cleaner, or can be indirectly communicated through the air outlet pipe 24 . The air flows in from the air inlet of the axial flow turbine 32 and the air inlet 30 of the dust suction duct at the same time, passes through the wind guide cover 31 in the driving air duct 26 to push the axial flow turbine 32 to rotate, and flows through the axial flow turbine 32 Then flow to the air outlet pipe part 24 along the connecting air duct 25 .

The axial-flow turbine 32 drives the driving gear 41 to rotate, and further, the driving gear 41 drives the reduction gear. The reduction gear drives the external gear 44 , and then drives the counter gear 46 to rotate. The reverse gear 46 further drives the internal gear 45 to rotate in reverse relative to the external gear 44 .

The inner base part 13 and the outer base part 14 are reversed around the same central axis, and the outer brush bar 38 raises the dust and hair, and the dust and hair enter the trumpet-shaped dust collection suction port driven by the suction airflow. If a hair is caught on the outer brush bar 38, the inner brush bar which rotates counterclockwise relative to the outer brush bar will pull the hair towards the end of the outer brush bar 38 every time it encounters the hair. The relative speed of the inner brush strip and the outer brush strip is about 4000 revolutions per minute, and there are more than one set of inner brush strips, and the number of pulls on the hair hanging on the outer brush strip reaches 8000 times or more per minute. It will always be pulled to the end of the outer brush strip and lifted by the inner brush strip, and finally fall into the airflow and be sucked away. If hairs get caught on the inner brush strip, they will also be stripped by the outer brush strip due to the same pulling action. 8,000 or more times of pulling per minute can realize the rapid exchange of hair between different brush strips, and finally peel it off the brush strips and fall into the airflow to be sucked away.

Function and effect of embodiment

According to the vacuum cleaner nozzle and the vacuum cleaner involved in this embodiment, since the inner base part, the outer base part, and the reversing mechanism are arranged in the vacuum cleaner nozzle, the inner base part and the outer base part can be reversed under the action of the reversing mechanism. Reversing each other around the same central axis, so that the outer cleaning part and the inner cleaning part can reverse each other, the hair and dust on the hard floor leave the hard floor due to suction, the hair and dust on the carpet are under the joint action of suction and the agitation of the outer brush bar In both cases, the dust and some hairs will enter the air duct to be sucked away, and some hairs may be clamped and grasped by the outer brush bars, and follow the rotation of the outer brush bars. Suction alone cannot It peels away from the outer bar, at which point the inner bar, which rotates counter-rotating relative to the outer bar, interacts with these pinched hairs, pulling them to the end of the outer bar and eventually letting them fall into the airflow where they are suck away. Therefore, when the user uses the suction nozzle of the vacuum cleaner in this embodiment and the vacuum cleaner to clean the dust and hair on the surface to be cleaned, the hair can actually enter the vacuum cleaner instead of being entangled inside the suction nozzle.

In addition, because the end of the inner brush strip is higher than the bottom surface of the frame, the end of the outer brush strip passes through the suction port, and the inner brush strip is inclined to the inlet of the dust suction duct, while the inner brush strip is farther away from the inlet of the dust suction duct It is closer, so after the inner brush bar strips the hair wrapped around the outer brush bar, the stripped hair is more likely to enter the airflow instead of being entangled inside the suction nozzle.
