Abstract
The invention relates to a fan which comprises a base (1) and a main body (2) arranged on the base. The main body comprises a spherical casing (4) with an opening (3), members arranged in the spherical casing and used for generating high pressure airflow, an air inlet (5) arranged on the spherical casing, an inner channel (10) used for receiving the high pressure airflow and an exhaust port (6) used for transmitting the high pressure airflow. Each member comprises an impeller cover (7), an impeller (8) and a motor used for driving the impeller to rotate to work. The high pressure airflow is transmitted from the exhaust port, and air on the outer portion of the fan is sucked by the airflow transmitted from the exhaust port through the opening. The fan has the advantages of being compact in structure, attractive in shape and the like.
Description
Technical field
The present invention relates to a kind of fan.
Background technique
The Japanese patent application that on December 23rd, 1981, publication number was the clear 56-167897A CN of JP (application number: clear 55-71978) disclose a kind of fan for generation of air stream, this kind fan comprises pedestal and the air sparge ring that is arranged on the pedestal, described pedestal comprises position member and the air inlet that is arranged on its bottom for generation of high pressure draught in the inner, described member comprises impeller and motor, described air sparge ring has inner passage and relief opening, described air sparge ring defines circular opening, passes through opening from the air-flow suction that the air in the fan external world is sent from relief opening.
The fan of this kind structure, the high pressure draught that its member produces are transported to that the average distance of relief opening is far away, and working efficiency is lower, and its outward appearance is not good in addition, and its use is very restricted.
Summary of the invention
The present invention aims to provide a kind of new fan to overcome above-mentioned defective of the prior art.The objective of the invention is to provide-kind of compact structure, efficient is higher and outward appearance is beautiful fan.
In order to achieve the above object, the technical solution used in the present invention is: for generation of the fan of air stream, described fan comprises pedestal and the main body that is arranged on the described pedestal, described main body comprises the spherical housing with opening, be arranged on the member for generation of high pressure draught in the described spherical housing, be arranged on the air inlet on the described spherical housing, be used for accepting the inner passage of described high pressure draught and the relief opening of the described high pressure draught of emission, described member comprises impeller chimney, the motor of impeller and the described vane rotary work of driving, described high pressure draught is launched by described relief opening, and the air of described fan outside is aspirated by the air-flow of launching from described relief opening by described opening.
Described high pressure draught refers to that air pressure is higher than the air-flow of described fan ambient air pressure.
Described spherical housing comprises spheroidal shell, elliposoidal shell, rugby shape shell, and described spherical housing also comprises the spherical housing of other form.
In a preferred embodiment, described spherical housing comprises front case part and back housing portion, and described front case part and described back housing portion limit described inner passage and relief opening together.
In another preferred embodiment, described impeller is positioned at described impeller chimney, and described impeller chimney comprises intake grill and exhaust outlet, and described intake grill is communicated with described air inlet, and described exhaust outlet is communicated with described relief opening.
Described impeller comprises receded disk impeller, diagonal flow type impeller.Described motor can be inner rotor motor, also can be external-rotor motor; Described motor can be the alternating current impression motor, can be DC Brushless Motor, can also be the motor of other form.
Described opening comprises circular opening, oval-shaped opening, and described opening comprises that also part is oval-shaped opening for circular opening, part.
Described fan can also comprise that this circuit control device can be arranged in the described spherical housing for the circuit control device of control motor rotary work.
The present invention has following good effect: the compact overall structure of apparatus of the present invention, and it is less to take up room; Its main body has spherical housing, and outward appearance is beautiful; Its relief opening and shorter for generation of the average distance between the member of high pressure draught, the transmission loss of its high pressure draught is lower, and efficient is higher; The larger member of overall dimensions is set in addition easily, and larger-size member is conducive to reduce the noise of its fan in spherical housing.
Description of drawings
Fig. 1 is the schematic representation of fan of the present invention.
Fig. 2 is the side schematic view of fan shown in Figure 1.
Fig. 3 is the sectional view that A-the A line intercepts along the fan shown in the figure l.
Fig. 4 is second embodiment of fan of the present invention.
Embodiment
Fig. 1 is the schematic representation from the fan of the present invention of device forward observation; Fig. 2 is the side schematic view of fan shown in Figure 1; Fig. 3 is the sectional view that A-the A line intercepts along the fan shown in the figure l.As seen, apparatus of the present invention comprise pedestal 1 and the main body 2 that is arranged on the pedestal 1 from Fig. 1, Fig. 2 and Fig. 3; Main body 2 comprises spherical housing 4, inner passage 10, relief opening 6 with opening 3, be arranged on impeller chimney 7, impeller 8, the motor 9 in the spherical housing 4 and be arranged on air inlet 5 on the spherical housing 4.
In the present embodiment, spherical housing 4 is the elliposoidal shell; Opening 3 is oval-shaped opening; Impeller 8 is the diagonal flow type impeller; Be fixedly connected with impeller chimney 7 after motor 9 and diffuser 11 are fixing, this diffuser 11 is the fixed tray form again; Air inlet 5 is the hole of grid; Main body 2 can be rotated certain angle at vertical plane relative to pedestal 1, thereby can change the air-out direction of main body 2 on vertical plane; The upper part 1a of pedestal 1 relatively lower part 1b swings, thereby can change the wind-out range of main body 2 on horizontal plane.
When this kind fan uses, it is positioned at the member operation work of the generation high pressure draught of spherical housing 4, air can be drawn into from the air inlet 5 that is positioned on the spherical housing 4, after boosting, the process member is transformed into high pressure draught, this high pressure draught is sent to inner passage 10 and relief opening 6 and is deflated mouthful 6 emissions, air from the fan outside is deflated mouthful 6 air-flow suctions of launching by opening 3, and the air-flow that is launched and the air-flow that is sucked combination are to produce the total air flow of launching forward from main body 2.
Fig. 4 shows second embodiment of fan of the present invention.Find out easily that from figure present embodiment is similar to previous embodiment, just the shape of the spherical housing 4 of present embodiment and opening 3 is different, and the spherical housing 4 of present embodiment is the spheroidal shell, and the opening 3 of present embodiment is circular opening.
Although showed and described and thought at present preferred embodiments of the invention, apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present invention that is limited by appended claims.
