Title: Electrical mosquito swatter with airflow generating means

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to home environmental hygiene and more specifically, to an electrical mosquito swatter with airflow generating means  
      2. Description of the Related Art  
      People may use an electrical mosquito swatter to kill mosquitoes and any other insets. However, when wielding the electrical mosquito swatter to make mosquitoes touch the electric surface, a wind pressure is produced. Because mosquitoes and insects are sensitive to wind pressure, mosquitoes and insets will soon fly away when the user is wielding the electrical mosquito swatter. Although a conventional electrical mosquito swatter has a broad electric surface, it still cannot kill mosquitoes and insects efficiently.  
     SUMMARY OF THE INVENTION  
      The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide an electrical mosquito swatter, which is controllable to generate a flow of air that forces insects to fly toward the electric surface.  
      To achieve this and other objects of the present invention, the electrical mosquito swatter comprises a swatter body, the swatter body comprising a handle and a frame fixedly connected to one end of the handle, an electric surface formed of positive and negative electric wires and stretched within the frame, an airflow passage defined within the frame around the electric surface, a plurality of air outlets formed on the frame in air communication with the airflow passage, a control switch set mounted on the handle, a battery mounted inside the handle and controllable by the control switch set to raise a voltage on the electric surface, and an electric fan mounted inside the handle and controllable by the control switch set to causes currents of air toward the airflow passage and the air outlets.

     DETAILED DESCRIPTION OF THE INVENTION  
      Referring to  FIG. 1 ˜ 3 , an electrical mosquito swatter in accordance with the present invention is shown comprising a swatter body  10 . The swatter body  10  has a handle  11  and a frame  14  at one end of the handle  11 . Positive and negative electric wires are stretched within the frame  14 , thereby forming an electric surface  15  for electrocuting any mosquitoes, insects, fly&#39;s, or any other pests on contact. A control switch set  12  is mounted on the handle  11 . A battery  13  is mounted inside the handle  11  and controllable by the control switch set  12  to raise voltage on the electric surface  15 .  
      Further, the handle  11  has an accommodation chamber  16 . An electric fan  17  is mounted inside the accommodation chamber  16  and electrically connected to the battery  13  through the control switch set  12 . The frame  14  provides an airflow passage  18  therein around the electric surface  15 , and has a plurality of air outlets  19  disposed on one side of the oval frame  14  around the electric surface  15  in air communication with the airflow passage  18 . The air outlets  19  slope in direction toward the electric surface  15 . The handle  11  further has a plurality of air inlets  20  on its one end for guiding in outside air.  
       FIG. 4  shows an alternate form of the present invention. This embodiment is substantially similar to the embodiment shown in FIGS.  1 ˜ 3  with the exception that the air outlets  19  are formed on both sides of the frame  14  around the electric surface  15  in air communication with the airflow passage  18 .  
      When in use, hold the handle  11  of the swatter body  10  and switch on the electric fan  17  and the electric surface  15 , and then wield the swatter body  10  to make mosquitoes touch the electric surface  15 . At this time, currents of air flow out of the air outlets  19  around the electric surface  15 . Therefore, a flow of air is produced around the electric surface  15  to force mosquitoes toward the center area of the electric surface  15 , and the user can kill mosquitoes and other inserts with the electrical mosquito swatter efficiently without wielding the electrical mosquito swatter with force.  
      Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
