Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: a novel food cover with an insect expelling structure comprises an outer insulation coarse net 1, a power grid 2 and an inner insulation fine net 3, wherein the outer insulation coarse net 1, the power grid 2 and the inner insulation fine net 3 are detachably mounted, larger pests in meshes of the outer insulation coarse net 1 can pass through the outer insulation coarse net, the larger pests can just contact with the power grid 2 to be electrocuted after passing through the meshes of the outer insulation coarse net, smaller pests in meshes of the inner insulation fine net 3 can not pass through the inner insulation fine net, the outer insulation coarse net 1 and the power grid 2 are tightly contacted with the inner insulation fine net 3 after being mounted, gaps are formed between the outer insulation coarse net 1 and the power grid 2 and between the power grid 2 and the inner insulation fine net 3, the gaps are very narrow and narrow, the pests cannot pass through the gaps, so that the dead pests can only remain in the meshes of the outer insulation coarse net 1, the pests can be beaten down by manually patting the food cover, the food cover is convenient to clean, wherein the outer insulation coarse net 1 and the inner insulation fine net 3 are stainless steel nets, plays the role of insulation and protection.

The bottom that is close to its edge on the thin net of internal insulation 3 wears to be equipped with bolt 4, and bolt 4 passes electric wire netting 2 and external insulation 1 back in proper order and threaded connection has nut 5, the dismouting of being convenient for, and the quantity of bolt 4 is three at least simultaneously, and each bolt 4 all is arranged as the centre of a circle by the center of the thin net of internal insulation 3 for the installation is firm between external insulation 1, electric wire netting 2 and the thin net of internal insulation 3.

The through-hole has been seted up at the middle part at external insulation coarse net 1 top, the inboard cover of through-hole is equipped with rubber circle 6, electronic transformer 7 is installed at the top of electric wire netting 2, electronic transformer 7's top is worn out behind the center of rubber circle 6 and is connected with power cord 8, the one end of power cord 8 is connected with plug 9, after putting through domestic power, electronic transformer 7 converts the electricity of alternating current into the pulse current of the high-voltage undercurrent that can kill the pest, when the pest wants to contact with electric wire netting 2 that has high-voltage pulse current, will electrocute and die. The high-voltage pulse current on the power grid 2 does not cause any harm to human bodies because the current is extremely low.

The working principle is as follows: when the novel food cover with the insect repelling structure is used, firstly, the outer insulating coarse net 1, the power grid 2 and the inner insulating fine net 3 are installed through the bolt 4 and the nut 5, then, a power supply is obtained through the plug 9, the electric of alternating current is converted into high-voltage low-current pulse current capable of killing pests through the electronic transformer, when the pests want to contact with the power grid 2 with the high-voltage pulse current, the pests get an electric shock and die, the pests with larger meshes of the outer insulating coarse net 1 can pass through the large pests, the pests just contact with the power grid 2 to be electrocuted after passing through the meshes of the large pests, the pests with smaller meshes of the inner insulating fine net 3 can not pass through the small pests, and the pests which die can only die in the narrow meshes of the outer insulating coarse net 1 because the outer insulating coarse net 1 and the power grid 2 and the gaps between the power grid 2 and the inner insulating fine net 3 are very big, and the pests can not pass through the small pests, at the moment, the pests can be patted down by patting the food cover with hands, and the food cover is convenient to clean.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
