Frequency-variable electronic removes the mite appearance

Technical field

The utility model relates to a kind of acarid and drives away equipment, especially relates to a kind of frequency-variable electronic and removes the mite appearance.

Background technology

Acarid is a kind of universal small insect, and kind has quite a few thousand kinds, and people's naked eyes are difficult to see clearly.Because they are prevalent in the environment of human living, data shows and is full of acarid harm among the household more than 75%, and the people in the whole nation about 1/4 has the irritated puzzlement of acarid.Acarid can cause the many allergy of human body, like allergic asthma, allergic rhinitis, allergic skin diseases etc., therefore receives extensive attention.The corpse fragment and the secretion of acarid are strong anaphylactogens, make the people produce anaphylactia, and the most outstanding will count allergic rhinitis, allergic bronchial asthma.Also can cause: diseases such as allergic dermatitis, acute urticaria, bronchitis, acne, whelk, conjunctivitis.Infantile baby is if contact the acarid of high concentration, and its trouble asthma probability will increase by 500 above, also can cause the illness of other high harmfulness of eczema or the like.

Acarid likes " dormancy " on the textile cloth article, and sheet, pillow, quilt, cloth sofa, carpet etc. all are the hotbeds that acarid grows.Wherein mattress, bed clothes, pillow are important breeding grounds.Dry skin or dandruff that human body can peel off 2 grams average every day automatically just enough make 2,000,000 acarids make a hearty meal.The fiber of the scurf of pet, mould, bedding and carpet and fragments all are the cuisines of acarid

According to statistics, acarid is laid eggs about more than 100 every day, and reproduction speed increases with geometry level.Specifically, an acarid survival surplus 1 gram house dust has 1000 approximately, its quantity can reach more than 10000 in the 1 gram bed clothes dust.In the use mattress for many years, the quantity of dirt mite is more than 2,000,000.

The irritated main performance of acarid has: allergic asthma, allergic rhinitis and inheritance hypersensitivity are wet examines.According to statistics, there are 80% asthma, rhinitis and allergic dermatitis relevant approximately with acarid allergy.

Chinese children asthma illness rate was about 5% in 2010, according to a preliminary estimate in state-owned about 1,800 ten thousand asthmatic children, the asthma patient more than 65% can produce allergy to acarid, about 80% childhood asthma results from acarid allergy.

Summary of the invention

The purpose of the utility model is to provide a kind of frequency-variable electronic to remove the mite appearance.

The utility model is provided with shell and removes the mite circuit with being loaded in the shell, and the said mite circuit that removes is provided with power-switching circuit, frequency conversion control circuit, waveform generator, power amplification output driving circuit, ultrasonic transducer and indicating circuit; The input external direct current power supply of said power-switching circuit; The output termination frequency conversion control circuit input of said power-switching circuit; The output welding wave generator input of frequency conversion control circuit; Waveform generator output termination power amplification output driving circuit input, power amplification output driving circuit output termination ultrasonic transducer and indicating circuit.

The utility model produces ultrasonic through the working method that adopts frequency conversion, intermittence and high-power output, and by the time circular flow of setting, thereby reach the purpose of driving away acarid, and can not make acarid produce adaptability.

The beneficial effect of the utility model is: acarid is indoor topmost anaphylactogen.Acarid can cause the many allergy of human body, like diseases such as allergic asthma, allergic rhinitis, allergic dermatitis, acute urticaria, bronchitis, acne, whelk, conjunctivitis, has 80% asthma, rhinitis and allergic dermatitis relevant with acarid approximately.The utility model frequency-variable electronic removes the mite appearance; Solve the killing indoor mite that exists in the prior art and drive away difficult problem; Can drive away indoor various acarid preferably, and can effectively suppress the feed and the breeding of acarid, thereby and can not make acarid produce adaptability. reach the purpose that reduces killing indoor mite quantity.It is easy to use, effect is obvious, and product does not contain any toxic chemical substance, meets the energy-saving and environmental protecting requirement, and people and pet are soon appointed harm.
