BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an electronic device, and more particularly to an air-flow generating device directly disposed on a lamp base. 
     2. Related Art 
     Nowadays, the concept of design is attracting more and more attention. As the household income gradually increases, people start to pay more attention to the household decoration and furnishing. “Illumination” is the most important element in the decorative design, and specifically, more than one set of lighting devices is disposed in almost every corner of a house including a living room, a dining room, a bedroom, and a washroom. 
     Indoor wiring for lamp bases is preplanned when the house is built, and positions for disposing the lamp bases cannot be easily changed at any time, so that the subsequent decoration and furnishing operations are mostly carried out to cater to the positions of the lamp bases, and meanwhile, the furnishing of the overall space is further considered. If a resident changes positions of furniture or even rearranges the usage of the indoor space at will according to his/her preferences, the preset lamp bases may not be suitable for the decoration and furnishing changed by the resident at will. As a result, a part of the lamp bases cannot achieve an optimal illumination effect. 
     A conventional lamp base for indoor use has a cup-shaped electrical connection base. The electrical connection base has an internal thread. A conventional bulb has a light-emitting body and a terminal portion. An external thread fitting with the internal thread of the electrical connection base is configured on an outer edge of the terminal portion, such that the terminal portion of the bulb can be directly screwed into the lamp base, so that a user can easily replace the bulb. 
     Currently, environmental awareness and energy conservation concepts have become hot topics and directions for research and development all over the world, and the consciousness of environmental protection and energy conservation has deeply rooted in people&#39;s daily life. Considering the selection of bulbs, traditional bulbs have been gradually abandoned, and instead, power-saving bulbs that consume less power are used, so as to achieve the energy conservation effects. In the year of 1997, many countries signed “Kyoto Protocol” in Kyoto, Japan, in which the countries agreed to jointly reduce the carbon emission (i.e., emission of carbon dioxide) and alleviate the severe influence caused by the greenhouse effect on the global climate. 
     In addition, if an indoor light device lost its original illumination effect due to the changing of the indoor furnishing, the resident is most likely to detach the bulb. In this way, the electrical energy is saved and unnecessary energy waste is avoided, and meanwhile, carbon dioxide produced when the bulb emits lights is further reduced. 
     However, after the bulb is detached from the lighting device, only a lamp base embedded in the wall is left, and the lamp base substantially has no function if it is not electrically connected to a bulb, which is a waste of both cost and resources. 
     Furthermore, as most people get used to using air conditioners or fans, and the global temperatures have been increasing in recent years, the ordinary household power consumption greatly increases due to the long-time usage of air conditioners or fans, which in turn exacerbates the global warming. As an air conditioner or fan mostly blows air in a specific direction and cannot blow air towards every corner of a house due to the restrictions of the arranged position thereof, the operating performance of the air conditioner or fan must be improved if a large-scale indoor air circulation is required. As a result, more power will be consumed, which does not conform to the environmental protection and energy conservation concepts that are currently advocated. 
     Therefore, it has become an issue that has been thought about by the applicant for a long time how to effectively utilize the lamp base that is not disposed with a bulb to derive new functions of the lamp base except the illumination function, for example, a function of generating an air flow for indoor air circulation, and meanwhile avoiding problems of infinite waste of global resources, rapid energy exhaustion, and rapid global warming. 
     SUMMARY OF THE INVENTION 
     Accordingly, the present invention is an electronic device, which can solve the problem in the prior art that a lamp base that is not disposed with a bulb cannot achieve its function, and result in a waste of manufacturing resources. 
     An electronic device is provided in the present invention, which is disposed on a lamp base, and comprises a connection base and an air-flow generator. The connection base has a threaded connecting portion on one side thereof, and the threaded connecting portion is connected to the lamp base. The air-flow generator is disposed on the connection base and used for generating an air flow. 
     The efficacy of the present invention lies in that, a lamp base that is not disposed with a bulb is changed to be electrically connected to a connection base provided with an air-flow generator for generating a air flow, so as to improve the indoor air circulation. Thus, a desirable ventilation effect is achieved in the entire environment, which is beneficial to the human health.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIGS. 1A and 1B  are schematic views of a first embodiment of the present invention. In this embodiment, an electronic device  100  disclosed in the present invention is disposed on an alternating current (AC) lamp base  200 . The AC lamp base  200  is a commonly used lamp base that matches with power-saving bulbs and has a spiral cup-shaped base therein. 
     The electronic device  100  comprises a connection base  110  and an air-flow generator  120 . The connection base  110  has a threaded connecting portion  111  on one side thereof, and a rectifier  112  is electrically disposed within the connection base  110 . The threaded connecting portion  111  has a male thread, and the lamp base  200  has a female thread matching with the male thread therein. The threaded connecting portion  111  may adopt standard lamp-cap specifications of commonly used screw-type bulbs, for example, E 11 , E 17 , E 27 , and other various household specifications (E means that the threaded connecting portion  111  is a screw-type connecting portion, and  11 ,  17 , and  27  are diameters of the threaded connecting portion  111 ), and match with the female thread of the lamp base  200 . The male thread is fitted with the female thread, such that the threaded connecting portion  111  is electrically connected to the AC lamp base  200 . At this time, the rectifier  112  receives an AC power supplied by the lamp base  200 , converts the AC power into a direct current (DC) power, and then outputs the DC power. 
     The air-flow generator  120  is an axial-flow fan, and is disposed on the other side of the connection base  110  opposite to the threaded connecting portion  111 . The air-flow generator  120  is electrically connected to the rectifier  112  to receive the DC power output by the rectifier  112  and generate an air flow, so as to generate air turbulence around the electronic device  100 . In addition, as shown in  FIG. 2 , the air-flow generator  120  disclosed in the present invention may also be selected as a centrifugal fan according to the practical usage requirements, and the centrifugal fan has two vents, so as to achieve different air turbulence effects around the electronic device  100 . However, it should be understood by those skilled in the art that, the centrifugal fan may also be designed to have more than three vents, so as to achieve an air turbulence effect required in an actual environment. 
     In addition to a rectangular structure as shown in  FIGS. 1 and 2 , a housing of the air-flow generator  120  may also be designed as circular, elliptical, triangular, square, hexagonal, octagonal, and other geometric structures, so as to match with the indoor decoration and beautify the indoor space, but it is not limited to the geometric shapes disclosed in this embodiment. 
     Referring to  FIG. 3 , an anion generator  130  may be further disposed at an air inlet of the air-flow generator  120 . The anion generator  130  is electrically connected to the rectifier  112 , so as to receive the DC power and release anions. The anions are dispersed outwards by the air flow generated by the air-flow generator  120  to purify the air in the surrounding environment. Referring to  FIG. 4 , the electronic device  100  of the present invention may further comprise at least one light emitting diode (LED)  140  disposed on an outer side of the air-flow generator  120 , and the LED  140  is electrically connected to the rectifier  112  to receive the DC power and generate light rays. 
     As shown in  FIG. 5A , in the present invention, an ultraviolet lamp  150  may also be disposed on the outer side of the air-flow generator  120 . The ultraviolet lamp  150  is electrically connected to the rectifier  112  to receive the DC power and generate ultraviolet rays for disinfecting the surrounding environment of the electronic device  100 . Referring to  FIG. 5B , a photocatalyst screen  160  corresponding to the ultraviolet lamp  150  may be further disposed at an air outlet of the air-flow generator  120 . When the ultraviolet lamp  150  emits ultraviolet rays for disinfection, the photocatalyst screen  160  receives the ultraviolet rays and a photocatalyst reaction occurs, and thus the ozone disinfection is carried out in the surrounding environment through the air flow generated by the air-flow generator  120 . Through the cooperation of the ultraviolet lamp  150  and the photocatalyst screen  160 , the environmental cleaning and disinfection effects are improved. 
     Referring to  FIG. 6 , the electronic device  100  of the present invention may also be disposed on an electrical socket  400  commonly used in ordinary households. In this embodiment, the threaded connecting portion  111  of the connection base  110  is electrically connected to an adapter  300 . The threaded connecting portion  111  has a male thread of standard lamp-cap specifications, and the male thread matches with and is fitted with a female thread within the adapter  300 . Two conductive terminals  310  are provided on the other side of the adapter  300  opposite to the threaded connecting portion  111 , and the two conductive terminals  310  are inserted into two jacks  410  of the electrical socket  400  to receive an AC power provided by the electrical socket  400 . At this time, the rectifier  112  in the connection base  110  converts the AC power into a DC power and outputs the DC power to the air-flow generator  120 , so as to enable the air-flow generator  120  to generate an air flow. 
     Referring to  FIG. 7 , as for the electronic device  100  in an eighth embodiment of the present invention, the threaded connecting portion  111  has an accommodation space  113  therein, and a through hole in communication with the accommodation space  113  is formed on the other side of the threaded connecting portion  111  opposite to the air-flow generator  120 . The threaded connecting portion  111  further comprises an electrical connection post  114  and an elastic element  115 . The electrical connection post  114  is inserted in the through hole, and is electrically connected to a lamp base (not shown). The elastic element  115  is disposed in the accommodation space  113  and is connected to a bottom end of the electrical connection post  114 , so as to elastically press against the electrical connection post  114  to protrude out of the threaded connecting portion  111 . 
     The electrical connection post  114  of the present invention may be moved reciprocatingly in the through hole through the elastic element  115 , which significantly improves the electrical connection between the electrical connection post  114  and the lamp base and enables the electronic device  100  to stably receive a current. As such, no short circuit or spark occurs at the electrical connection post  114 , thus increasing the safety of the electronic device  100  in use. 
     The elastic element  115  in the eighth embodiment of the present invention is a compression spring. However, it should be understood by those skilled in the art that, any elastic material that can be elastically deformed and generate a restoring force may be selected such as a washer, but the present invention is not limited here. 
     Referring to  FIG. 7 , the air-flow generator  120  further comprises a flow guide portion  121  therein, and at least one vent  122  corresponding to the flow guide portion  121  is opened on a side wall of the air-flow generator  120 . One side of the flow guide portion  121  facing the fan blades  124  is a camber for guiding the air flow towards the vent  122 , so as to generate air turbulence around the electronic device  100 . A filter material may be additionally provided at the vent  122  to purify the air in the surrounding environment. 
     The air-flow generator  120  further comprises at least one damping washer  123  disposed adjacent to the fan blades  124 , so as to absorb the vibration energy produced when the fan blades  124  rotate and the shear energy produced when the air flow is guided to the flow guide portion  121 , thereby reducing the noises generated during the operation of the air-flow generator  120 . 
     The electronic device of the present invention is electrically connected to a lamp base, so as to effectively utilize the unused lamp base, thereby avoiding unnecessary waste of resources, and satisfying carbon reduction requirements specified in “Kyoto Protocol”. Meanwhile, the air flow generated by the air-flow generator may cause the indoor air to flow, so as to improve the air ventilation in the entire environment. 
     The electronic device of the present invention may be additionally equipped with an anion generator, an ultraviolet lamp, a photocatalyst screen, as well as other components, so as to disinfect the living environment through the air flow generated by the air-flow generator, which is beneficial to the human health.
