The present invention has a function as an electric fan and a function of eliminating a mosquito, so that it is possible to obtain a remarkable effect in the summer when the heat and the mosquito are struck, and the safety of the user can be ensured at the time of use, The technical features.

For this purpose, the present invention is characterized in that a mosquito repelling ring (10) in the form of a strip that emits a mosquito repellent incense which a mosquito dislikes, as shown in FIG. 2, is provided.

The mosquito repellent ring 10 is provided on the side net 6 or the handle 7 and is preferably fitted and fixed in the form of wrapping the side face or the outer periphery of the handle. In order to facilitate the understanding of the present invention, the mosquito repelling ring 10 is shown coupled to the side net 6.

Here, the mosquito repellent incense refers to a fragrance extracted from a fragrance incompatible with mosquitoes, for example, herbs, sheet rolls, lavender, peppermint, lemon grass, geranium, eucalyptus, The mosquito repellent ring 10 may be manufactured through a variety of methods or processes and may be adapted to emit a mosquito repellent incense.

Conventionally, in the outdoor activity in the summer, when the user wears a bracelet for mosquito repellent on the wrist, a handy fan must be operated to achieve a cooling effect and a mosquito repellent effect. Since the mosquito repellent incense is diverted from the mosquito repelling ring to the vicinity of the user, the present invention can obtain a remarkable effect of blocking the approach of the mosquito to the vicinity of the user by the cooling effect and the cooling effect even when the user hangs on his / It is possible to reduce the burden of the cost that must be all purchased, and to provide the convenience of the user sufficiently.

The mosquito repulsion ring 10 is made of a material having elasticity and elasticity (for example, rubber or silicone material) and can be formed in various colors. The mosquito repulsion ring 10 can be formed into various shapes, images, phrases, (Not shown) may be further provided.

Conventional handheld fans are manufactured in a single color and flat design and are monotonous and can not provide aesthetics at all. The mosquito repellent ring of the present invention is formed of a material having elasticity and elasticity, and can be easily attached to the side net or the handle with various ornamental parts of various colors or various forms. When the mosquito repellent incense is completely exhausted, The mosquito repellent ring can be easily installed and replaced at any time according to the user's need, such as when it is desired to change, so that a variety of colors can be expressed, an aesthetic feeling can be maximized, and consumers' desire to purchase can be increased.

In addition, although not shown in the drawing, the mosquito repulsion ring 10 can be fixed to the handle by fixing the mosquito repellent ring to the outer circumferential surface of the handle. In this case, the mosquito repellent ring protrudes when the handle is gripped, Can occur. In addition, when children use an electric fan, the mosquito repelling ring can be forcibly removed, thereby causing a problem that the mosquito repelling function is lost. Therefore, it is preferable to form a recess having a shape corresponding to the mosquito repelling ring along the outer circumferential surface of the handle to prevent it from projecting outward.

4, the side net 6 according to the present invention includes a fragrance inflow hole 30 for diffusing the mosquito repelling incense emitted from the mosquito repelling ring 10 to the front of the fan, .

The fragrance inflow hole 30 may be formed in a plurality of spaces at regular intervals on the side net 6 so that more mosquito repellent incense can be introduced into the safety net, and the diameter may be lengthened or shortened according to the width of the side net .

In the absence of the fragrance inflow hole 30, the mosquito repellent fragrance emitted from the mosquito repellent ring 10 is mixed with air and gradually moved in accordance with the flow of the air. However, the mosquito repellent fragrance flows into the safety net through the fragrance inflow hole 30 In this case, it is possible to prevent the mosquitoes from approaching more effectively because they are transmitted quickly and far to the front of the fan along with the wind formed during the rotation of the wings. For example, when a fan is turned on the user's body or face, the mosquito repellent smell is added to the body or clothes, thereby further improving the mosquito repellent effect.

Next, the present invention includes a diffusion ring 40 extending in a predetermined width along the rear edge of the front net 4 and coupled to the front net of the side net 6 so as to be pulled forward .

In this case, it is preferable that the mosquito repulsion ring 10 is coupled so as to surround the outer peripheral surface of the diffusion ring, and the recessed groove 41 and the fragrance inflow hole 42 are formed on the outer peripheral surface of the diffusion ring.

5 to 6, the diffusion ring 40 extends a region for collecting and concentrating the wind formed at the time of rotation of the vane 2, so that the side net 6 and the diffusion ring 4 Continuously pass through to enhance the straightness, so that the mosquito repellent smell is transmitted farther.

When the diffusion ring 40 is drawn out, the region for gathering the wind is expanded, and the pressure is increased inside, so that the effect of increasing the straightness of the wind at the time of discharge can be remarkably increased.

The diffusion ring 40 may be drawn out from the side net 6 in various ways.

5, guide grooves 50 are formed in a spiral shape along the inner circumferential surface of the diffusion ring 40. The outer circumferential surface of the side net 6 is provided with a stopper (60) may be formed. Although not shown, guide grooves are formed in a spiral shape along the inner circumferential surface of the side net, and a stopper that moves along the guide grooves may be formed on the outer circumferential surface of the diffusion ring. When the user holds the rear net 5 or the knob 7 with one hand and rotates the diffusing ring 40 with the other hand, the diffusion ring 40 Can be quickly and easily pulled out while being rotated in the form of a spiral, and it is possible to prevent a problem that the durability is deteriorated or broken by preventing a large force from being applied to other parts at the time of drawing.

When the diffusion ring 40 and the side net 6 are engaged with each other through the guide groove 50 and the stopper 60, the diffusion ring 40 is prevented from being drawn out by the external force, can do. For example, if the guide groove is formed in a straight line, when the rear net 5 is pressed while the front ring 4 is facing the ground in a state that the diffusion ring 40 is drawn out, 60 are moved from one side to the other side without any restriction along the guide groove and the diffusion ring is pulled in. Therefore, when the diffusion ring is used, it is troublesome to pull out the diffusion ring again. In contrast, according to the present invention, since the diffusion ring 40 is supported by the stopper 60 that moves on the helical guide groove 50, the diffusion ring 40 is not arbitrarily inserted, It is possible to ensure the convenience of use and to prevent breakage of the product.

As described above, the mosquito repulsion ring 10 of the present invention has a remarkable effect of improving the grip feeling through the effect of blocking the approach of the mosquito to the vicinity of the user, the improvement of the esthetics and the increase of the frictional force at the time of withdrawing the diffusion ring, The handy type fan having the mosquito repellent function according to the present invention having the mosquito repellent ring is advantageous in practicality, economy, and convenience because it can simultaneously obtain the effect of eliminating the mosquito while providing cool wind in the outdoor activities in summer.
