Abstract
An air inlet structure of an electric fan for a dust collector belongs to the technical field of electric fans and comprises a fan and a fan cover connected with the fan through a connecting piece. A fan impeller is arranged on a transmission shaft of the fan and located in the fan cover, the front end of the transmission shaft of the fan is located outside the fan cover, a transmission wheel is arranged at the front end of the transmission shaft, and an air inlet is arranged at the bottom of the fan cover in a matching mode. By means of the technology, the extended shaft portion and the transmission wheel are arranged outside the fan cover of the electric fan, floor hairbrushes of the dust collector work through belt transmission simultaneously and brush away dirt, and then the dirt is sucked by air holes on the fan cover into the dust collector, thereby achieving the dust-removing and dust-collecting effect. The air inlet structure is compact in structure, low in cost and high in efficiency, the dust-removing and dust-collecting movements are performed simultaneously, the stability and the high efficiency of an air draft system of the electric fan are guaranteed, the work efficiency of the electric fan is improved wholly, and the service life of the electric fan is prolonged.
Description
Technical field
The utility model belongs to the electric fan technical field, is specifically related to a kind of compact structure, cost is low, efficient the is high vacuum cleaner air inlet structure with electric fan.
Background technique
In the household electric appliance of Modern Family, vacuum cleaner is one of requisite electrical equipment.Domestic vacuum cleaners in the market are in order to improve pick-up performance, and the intake grill that all is employed in vacuum cleaner is installed a ground hair brush structure, through the ground hairbrush ground dust cleaning is sucked by vacuum cleaner more easily, has improved pick-up performance and efficient.Drive in the vacuum cleaner that uses at present, it is inconvenient and unstable aspect structure and electronic control, to exist, and cost is also higher, and the operating life of two motors of scrubbing brush motor and motor of dust collector also exist different, thereby influence the work of whole vacuum cleaner.
The model utility content
To the problems referred to above that exist in the existing technology, the purpose of the utility model is being specifically related to a kind of compact structure, cost is low, efficient the is high vacuum cleaner air inlet structure with electric fan.
Described a kind of vacuum cleaner is with the air inlet structure of electric fan; Comprise blower fan and the fan housing that is connected through link with blower fan; The transmission shaft of blower fan is provided with fan blade, and this fan blade is positioned at fan housing, it is characterized in that said blower fan transmission shaft front end is positioned at outside the fan housing; Front end at transmission shaft is provided with drive wheel, and described fan housing bottom is equipped with intake opening.Described a kind of vacuum cleaner is characterized in that being equipped with driving belt on the described drive wheel with the air inlet structure of electric fan.
Described a kind of vacuum cleaner is characterized in that with the air inlet structure of electric fan described fan housing comprises the cover seat and is mated the cover cap that is connected, and described cover seat is connected through link with blower fan, and the cover cap center is equipped with the wind hole.
Above-mentioned a kind of vacuum cleaner is with the air inlet structure of electric fan; Comprise blower fan and the fan housing that is connected through link with blower fan; The transmission shaft of blower fan is provided with fan blade, and this fan blade is positioned at fan housing, and blower fan transmission shaft front end is positioned at outside the fan housing; Front end at transmission shaft is provided with drive wheel, and described fan housing bottom is equipped with intake opening.Described a kind of vacuum cleaner is characterized in that being equipped with driving belt on the described drive wheel with the air inlet structure of electric fan.Through adopting above-mentioned technology, the utility model has solved above-mentioned limitation of the prior art, provides a kind of and the projecting shaft part is set outside the fan housing of electric fan and a drive wheel is installed; Utilize belt transmission that the ground hairbrush of vacuum cleaner is worked simultaneously; The ground hairbrush is brushed foul, sucks vacuum cleaner by the wind hole on the fan housing, reaches the effect of dedusting dust suction; This compact structure, cost is low, efficient is high; And dedusting and dust suction action are carried out synchronously, have ensured the stable and high efficiency of electric fan air draft system, and integral body has improved the working efficiency and the working life of electric fan.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-fan blade, the 2-link, the 3-blower fan, 4-wind hole, 5-fan housing, 501-cover seat, 502-cover cap, 6-transmission shaft, 7-drive wheel, 8-driving belt.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but the protection domain of the utility model does not receive the restriction of embodiment.
As shown in Figure 1; A kind of vacuum cleaner comprises blower fan 3 and the fan housing 5 that is connected through links such as bolt 2 with blower fan 3 with the air inlet structure of electric fan, and the transmission shaft 6 of blower fan 3 is provided with fan blade 1; This fan blade 1 is positioned at fan housing 5; Said blower fan 3 transmission shafts 6 front ends are positioned at outside the fan housing 5, are provided with drive wheel 7 at the front end of transmission shaft 6, and described fan housing 5 bottoms are equipped with intake opening 4.Be equipped with driving belt 8 on the described drive wheel 7, be connected, when blower fan 3 work with scrubbing brush on the vacuum cleaner; Drive transmission shaft 6 and rotate, under the drive of transmission shaft 6, fan blade 1 rotates with drive wheel 7; Driving belt 8 on the drive wheel 7 drives scrubbing brush and rotates, and heavier particle and the stupid stain of cleaning floor surface washed away, after having cleaned; Rotate wind-force 4 entering that produce by fan blade 1, dust and rubbish are sucked, reach the purpose of dust suction dedusting from the wind hole.
The utility model passes fan housing 5 sides through transmission shaft 6 front ends are prolonged, and front end is provided with drive wheel 7; Form a complete dust collecting system with the fan blade, the fan housing that are installed in the fan housing and be socketed in transmission shaft 6; Rotation when fan blade 1 is with drive wheel 7 when machine operation, 5 ones of fan housings produce vacuum, form high draught head with outside atmosphere; Outer gas stream is inhaled into; The hairbrush that while drive wheel 7 is crossed the installation of belt transmission vacuum cleaner intake grill washes away floor surface heavier particle and stupid stain, and with reaching dust suction and dedusting suburb fruit in the air-flow suction vacuum cleaner, increases work efficiency.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
