Abstract
The invention discloses a bladeless fan. The bladeless fan comprises a base seat, a machine housing and an air concentrator, wherein a rubber sleeve is arranged in the machine housing, the rubber sleeve is filled with magnetic liquid, the rubber sleeve sleeves the exterior of an annular exciting coil, the rubber sleeve can further be inserted into the annular exciting coil, the annular exciting coil is connected with a power connector, the power connector is connected with a pulse power source, pulse currents pass through the annular exciting coil so as to form a pulse electromagnetic field, the magnetic liquid generates progressing waves under functions of the pulse electromagnetic field, the progressing waves enable the rubber sleeve to continually wriggle, compel air to be sucked from the lower portion of the machine housing and accelerate the air, and then the air is ejected from the upper portion of the machine housing at high speed. Magnet powder in the magnetic liquid can be replaced with iron powder. The rubber sleeve is manufactured by using rubber high in elasticity and high in tenacity. The bladeless fan can not generate noise which can be brought by a motor, and solves the problem of high cost.
Description
Technical field
The present invention relates to a kind of fan, in particular, it about a kind of without leaf, without the fan of motor.
Background technique
At present, that on market, sells all has motor without blade fan, and its deficiency is that the large and price of noise has blade fan higher relatively.
Summary of the invention
The object of the invention is to overcome shortcoming of the prior art, provide a kind of do not have motor without blade fan.
Object of the present invention is achieved by following technical proposals.
Of the present inventionly without blade fan, comprise base, casing, blowing head, rubber sleeve in described casing, in described rubber sleeve, be filled with magnetic liquid, described rubber sleeve is in the outside of annular field coil, described rubber sleeve also can be in the inside of annular field coil, institute's art annular field coil is wanted to be connected with power connection, described power connection is connected with pulse power supply, impulsive current forms pulse electromagnetic field by described field coil, magnetic liquid produces traveling wave under described pulsed magnetic field action, make described rubber sleeve constantly " wriggling ", force air from described casing bottom, suck and accelerated, and to spray from top at a high speed.Magnetic iron powder in described magnetic liquid can replace with iron powder.What described rubber sleeve adopted is the rubber of high elasticity and high tenacity.
The present invention's advantage is compared with prior art:
1. simple in structure, be easy to manufacturing, cost is lower;
2. the noise that does not have motor to produce.
Accompanying drawing explanation
Accompanying drawing is a kind of embodiment's of the present invention structural representation.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
In the drawings, base 3, casing 2, blowing 1 links together, field coil 5 with rubber sleeve 4 in casing 2 and field coil in rubber sleeve 4.When field coil 5 energising produces pulse electromagnetic field, the magnetic liquid 7 in rubber sleeve 4 produces traveling wave under pulse electromagnetic field action, and rubber sleeve 4 is sprayed to top so that the mode of " wriggling " is air-breathing from the suction port 6 of casing bottom.What rubber sleeve 4 adopted is the rubber of high elasticity and high tenacity.In order to reduce costs, the magnetic iron powder in magnetic liquid 7 can replace with iron powder.
Claims (3)
1. one kind without blade fan, comprise base, casing, blowing head, it is characterized in that, rubber sleeve in described casing, liquid is magnetic in described rubber sleeve, described rubber sleeve is in the outside of annular field coil, institute's art annular field coil is wanted to be connected with power connection, described power connection is connected with pulse power supply, impulsive current forms pulse electromagnetic field by described field coil, magnetic liquid produces traveling wave under described pulsed magnetic field action, make described rubber sleeve constantly " wriggling ", force air from described casing bottom, suck and accelerated, and to spray from top at a high speed.
2. according to claim 1 without blade fan, it is characterized in that, the magnetic iron powder in described magnetic liquid can replace with iron powder.
3. according to claim 1 without blade fan, it is characterized in that, described rubber sleeve is in annular field coil the inside.
