Mite Predators ( also known as Mite Predators, Ultrasonic Mite Predators) can kill and suck out mites. Generally, the function of tapping + vacuuming + ultraviolet light is used to remove mites. Mite Predators can generate up to 40000Hz ( Hertz) Ultrasound that cannot be heard by the human ear. The mites remover uses the unique frequency of ultrasonic waves on the physiological system of the mites to make them resonate, which can effectively inhibit the feeding and reproduction process in the life cycle of dust mites, thereby reducing the density of dust mites and allergens in the space, reducing mite allergies and mites Allergic asthma attack is harmless to humans and pets, thereby solving the problem of dust mite control existing in the prior art.

1. Collection and screening of household dust mites Collect household dust mites from the natural environment. According to the habit of mites with photophobia, they are moved into mites by short-term irradiation with fluorescent tubes, and separated and collected into mites with a writing brush under an optical microscope.

2. Irradiation miticide test Place 25 adult mites in a glass vessel with a diameter of 125px and a height of 50px, and place the handheld ultraviolet sterilizer directly above the large glass vessel (50px away from the mites) for irradiation. The irradiation method is carried out according to the product manual. The irradiation dose and grouping are determined according to the results of the pre-test, that is, 3 irradiation dose groups are set: 4.83min, 7.0min and 9.0min respectively at the distance of the hand-held UV sterilizer.

EN 61000-3-3: Electromagnetic compatibility (EMC). Part 3-3: Limits. Limitation of voltage fluctuations and flicker in public low-voltage supply systems (for equipment with rated currents less than and equal to 16A)

Application process for CE certification of mite removal device :

Step 1: Apply for Application

1. Fill out the application form

2. Application company information form

3. Provide product information EMC LVD: circuit diagram + manual + BOM + Label (nameplate) + PCB board diagram + component certificate + motor + transformer specification, etc. (depending on the product)

Step 2: Quote Quotation

Determine the test standard, test time and corresponding cost according to the information provided

Step 3: Pay Pay

After the applicant confirms the quotation, signs the service agreement and pays the full project fee

Step 4: Test Testing

The laboratory conducts a full set of tests on the applied products and difference tests of related models according to the relevant EU testing standards

Step 5: The test is passed and the report is completed

Step 6: The project is completed and the CE certificate is issued

Information required for CE certification of the mite remover :

1. Instructions for use of the product;

2. Safety design documents;

3. Product technical conditions;

4. The electrical schematic diagram of the product;

5. Product circuit diagram;

6. List of key components or raw materials, etc.

CE certification requirements:

1. Products must not be harmful to health, the environment and consumers before they can be circulated in the market.

2. Products legally marketed in one EU country can also be sold in other member states.

By affixing the EU CE certification mark on the product, the manufacturer indicates that the product fully complies with the relevant provisions of the EU Directive. If permitted by regulations, the CE mark may also be indicated on the packaging or accompanying documents.

The EU CE certification mark is not a test mark, but only indicates that the manufacturer declares that its product complies with all relevant regulations. Currently, there are various conformity assessment models to mark compliance with basic requirements, which may involve several units, such as manufacturers, importers, and distributors. If you want to apply for CE certification, indicating that the product meets the standard, you still need to find a third-party testing agency for certification.

What is the significance of CE certification?

1. CE certified products can improve product competitiveness;

2. When the product is out of customs, it can be free from the risk of being detained;

3. Reduce the risk of being investigated and dealt with during inspections;

4. Once the product is investigated and dealt with, the third-party testing agency will take part of the responsibility, so the risk will be reduced;

5. Consumers will trust products with CE certification marks more when purchasing products;

6. The products affixed with the CE certification mark represent the product responsible for the standard regulations, and are also a guarantee of safety;

CE certification provides a unified technical specification for the trade of products from various countries in the European market and simplifies the trade procedure. Products from any country must be CE certified to enter the EU, and the CE mark must be affixed to the product. Therefore, CE certification is a passport for products to enter the European Union and European Free Trade Zone countries. CE certification means that the product has met the safety requirements specified by the EU directive; it is a commitment of the enterprise to the consumer, which increases the consumer's trust in the product; products with the CE mark will reduce the risk of being sold in the European market. These risks include:

A. The risk of being detained and investigated by the customs;

B. The risk of being investigated and dealt with by market supervision agencies;

C. Risk of being accused by peers for competitive purposes.
