A bladeless fan, also known as an air multiplier, is a new type of fan that uses an air pump in the base to suck air in, accelerate it through a specially designed pipe, and finally blow it out through a bladeless annular air outlet to achieve a cooling effect. Bladeless fans are gradually favored by the market because of their safety, easy cleaning, and gentle wind.
Quality Key Points for Third-Party Inspection of Bladeless Fans
Appearance quality: Check whether the product appearance is clean, without scratches or deformation, and whether the color is uniform.
Functional performance: Test whether the fan's starting, speed adjustment, timing and other functions are normal, and whether the wind force is stable and uniform.
Safety performance: Confirm whether the product has passed relevant safety certifications, such as CE, UL, etc., and check whether there are safety hazards such as leakage and overheating.
Material quality: Check whether the materials used in the product meet the requirements, such as the hardness and toughness of plastic parts, the rust prevention and anti-corrosion of metal parts, etc.
Packaging identification: Check whether the product packaging is intact and whether the identification is clear and accurate, including product model, production date, instructions for use, etc.
Preparation for third-party inspection of bladeless fans
Understand inspection standards: Be familiar with national standards, industry standards and customer-specific quality requirements for bladeless fans.
Prepare inspection tools: Prepare necessary inspection tools, such as multimeters, screwdrivers, timers, etc.
Develop an inspection plan: Develop a detailed inspection plan based on order quantity, delivery time, etc.
Bladeless fan third-party inspection process
Sampling inspection: randomly select samples from the entire batch of goods according to a predetermined sampling ratio.
Appearance inspection: Conduct appearance inspection on the sample, including color, shape, size, etc.
Functional performance test: test the functional performance of the sample, such as wind force, speed range, timing accuracy, etc.
Safety performance test: Carry out safety performance test, such as withstand voltage test, leakage test, etc.
Material quality inspection: Check the quality of the materials used in the sample, such as the hardness and toughness of plastic parts, etc.
Packaging and labeling inspection: Check whether the packaging and labeling of the sample meet the requirements.
Records and reports: record inspection results, write inspection reports, and notify customers of the results in a timely manner.
Common quality defects in third-party inspection of bladeless fans
Unstable wind: It may be caused by problems with the fan's internal design or manufacturing process.
Excessive noise: It may be caused by loose, friction or unreasonable design of the internal parts of the fan.
Safety hazards: such as leakage, overheating, etc., may be caused by improper circuit design or material selection.
Packaging damage: It may be caused by squeezing or collision during transportation.
Precautions for third-party inspection of bladeless fans
Strictly abide by inspection standards: ensure that the inspection process is fair, objective and free from interference from any external factors.
Carefully record the inspection results: Record the inspection results of each sample in detail for subsequent analysis and improvement.
Timely feedback on problems: If quality problems are discovered, timely feedback should be provided to customers and assist customers in solving the problems.
Protection of intellectual property rights: During the inspection process, attention should be paid to protecting customers' business secrets and intellectual property rights.
Maintain communication with customers: Maintain good communication with customers and understand customer needs and feedback in a timely manner to provide better inspection services.
