ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a switchable mosquito expelling/killing device which can be switched between a mosquito expeller for expelling mosquitoes and an electric mosquito incense device for killing the mosquitoes. The switchable mosquito expelling/killing device is applicable to various outdoor situations such as camping, mountaineering, etc.
It is known that mosquitoes are harmful insects which bite people and are media of various kinds of infectious diseases such as Japanese encephalitis, dengue fever, malaria, etc. Therefore, it is important to kill the mosquitoes.
In general, the mosquitoes are killed by means of mosquito incense or pesticide. Such measures will result in stimulating odor which is hard to bear. In addition, the above measures are usable indoors. In the case that they are used outdoors, the incense tends to dissipate with wind and the mosquito-killing can be hardly achieved.
In order to improve the stimulating odor produced by the mosquito incense or pesticide, electric mosquito incense device and mosquito expeller have been developed. With respect to the electric mosquito incense device, a heater is used to heat an electric mosquito incense mat so as to release a gas for killing or expelling the mosquitoes. Those mosquitoes which will attack people or animals are female mosquitoes during egg laying period. The female mosquitoes during this period will avoid male mosquitoes. The mosquito expeller employs this principle to generate a sound wave simulating the sound produced by the male mosquitoes and thus expel the female mosquitoes. The above two measures have their intended functions, and therefore one measure is not convertible to the other because of the external environment or factors. For example, in case the electric mosquito incense mat is exhausted and no spare is available, the electric mosquito incense device will become useless.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a switchable mosquito expelling/killing device which has simple structure and can be easily carried.
It is a further object of the present invention to provide the above switchable mosquito expelling/killing device which can be switched between a mosquito expeller and an electric mosquito incense device in accordance with environmental factors.
It is still a further object of the present invention to provide the above switchable mosquito expelling/killing device which is able to protect a user from being bitten by mosquitoes.
According to the above objects, the switchable mosquito expelling/killing device of the present invention includes a box body having a clip for hanging the box body on a user's body. The box body is disposed with a pushing block, an electric mosquito incense mat insertion hole, gas releasing slots and a switch. An oscillating circuit and a heater fixing seat, an electric heater and a cell for supplying power are disposed in the box body. By means of switching the switch, the mosquito expelling/killing device can be switched between a mosquito expeller using the oscillating circuit to generate a sound wave simulating the sound wave of male mosquitoes for expelling fertilized female mosquitoes and an electric mosquito incense device using the electric heater to heat electric mosquito incense mat for releasing mosquito-killing incense to kill the mosquitoes.
The present invention can be best understood through the following description and accompanying drawings wherein:
