Description
Technical field
The utility model relates at present known various electric fans, and particularly a kind of pair of wind wheel collection wind public attention blade-free electric fan needs air circulation to flow and the place of cooling to be applied in room, office or other quieter, more attractive in appearancely.
Background technique
Known various electric fans comprise a blowing blade-free electric fan patent No. 200910154890.0 of my invention at present, all exist variety of issue, 1; Usually the principle of fan for cooling blowing is that driven by motor has the fan blade of several angle to rotate; allow air circulation flow to take away the cooling device of heat; this cooling device can be divided into two large classes; a kind of is the leafy ceiling fan that fan blade is directly exposed to the outside; another kind is that the fan blade outside has the removable electric fan of safety cover; our common table fan and ground electric fan namely; the defective of the mobile cooling device of the air circulation of these two large types is that the air stream that the fan blade rotation produces can allow the user feel inhomogeneous; this main cause is that fan blade inclined-plane cutting air produces wave air-flow result; airflow noise is very noisy; extremely not convenient in cleaning process; the volume of packing is difficult to dwindle; safety for the people can not guarantee, and outward appearance is difficult to change traditional shape.2; A blowing blade-free electric fan patent No. 200910154890.0 of my invention has solved to a certain extent above-mentioned electric fan and has had technological deficiency, but existing the noise decibel crosses high defective.
Summary of the invention
For this reason the utility model for existing electric fan exist outer shape single, clean inconvenience, packaging volume is large, the blade-free electric fan patent No. 200910154890.0 noise decibels without a head of drying are crossed high technological deficiency, and a kind of two wind wheel collection wind public attention blade-free electric fans that reduce noise are provided.
In order to realize reducing noise and the blowing head has enough air quantity to blow out, of the present utility model pair of wind wheel collection wind public attention blade-free electric fan adopted technological scheme and comprised base, main motor, head-shaking motor, lower shell body, the first wind wheel, the first spiral case, blowing head, the second spiral case, the second wind wheel.
Further improve as the utility model, the blowing head is connected with a blowing base consubstantiality, a blowing base is connected with lower housing top is detachable, the blowing head is to dwindle packaging volume with the detachable advantage that is connected in lower shell body upper end, simultaneously the blowing an interchangeable difformity of making, blowing four circle are hollow air channels, and lower shell body has intake opening.
Further improve and optimization as the utility model, the first wind wheel and the second wind wheel are equipped with respectively in the two ends of main motor shaft, described the first wind wheel is connected to by the first wind wheel safety above the end of main motor shaft, and described the second wind wheel is connected to above the other end of main motor shaft by the second wind wheel safety.
As optimal design, the first spiral case is equipped with in the first wind wheel of the present utility model outside, and the second spiral case is equipped with in the second wind wheel outside, and the one side of the first spiral case is integrated and connected with the one side of the second spiral case, the another side of the first spiral case is the first intake grill, and the another side of the second spiral case is the second intake grill.
As further improvement of the utility model, main motor is installed in the middle of the first spiral case and the second spiral case joint, and the first exhaust outlet of the first spiral case and the second spiral case the second exhaust outlet are integrated and form the collection air port, and the collection air port is installed in below the blowing head bottom.
As optimal design, be installed in the lower shell body the inside behind the first spiral case and the second spiral case, main motor, the first wind wheel, the second wind wheel integrated.
As optimal design, base and lower shell body lower end are flexibly connected, and head-shaking motor is installed in above the base bottom.
Working principle of the present utility model is such; Opening power master's electrical power rotates, main electric machine rotation also drives the first wind wheel and the rotation of the second wind wheel that the main motor output shaft two ends connect simultaneously, because the first spiral case and the second spiral case being housed respectively the outside of the first wind wheel and the second wind wheel, the one side of the first spiral case is integrated and connected with the one side of the second snail, the another side of the another side of the first spiral case and the second snail is the first intake grill and the second intake grill, cause the first wind wheel and the second wind wheel are under main motor high speed rotating drives, make air stream from the lower shell body intake grill, sucked by the first wind wheel and the second wind wheel from the first intake grill and the second intake grill respectively, simultaneously because of wind wheel and spiral case special construction and effect, make by the air that sucks under the first wind wheel and the second wind wheel high speed rotating, in the first spiral case and the second snail, be formed with the certain pressure air-flow, go out from the first spiral case exhaust outlet and the second exhaust outlet, there is the certain pressure air-flow to blow to a blowing hollow air channel by the collection air port, make blowing four circle have high wind to blow out, realized the purpose of two wind wheel collection wind public attention blade-free electric fans.
As further improvement of the utility model, adopt two wind wheel collection wind that airflow pressure is increased, but motor speed have certain decline, has so also reduced simultaneously fan noise.
When electric fan need to swing blowing, connect the head-shaking motor power supply, at this moment head-shaking motor rotates to drive with it and is connected the rotation of gear or connecting rod, has realized a blowing left-right rotation blowing purpose.
