It is difficult for traditional toothbrushes to completely remove dental plaque, and improper brushing methods greatly reduce the cleaning effect of toothbrushing. Electric toothbrushes can effectively reduce tooth stains caused by drinking tea, coffee and poor oral conditions, and restore the original color of teeth.

Since electric toothbrushes are superior to traditional toothbrushes, their users are becoming more and more popular. However, the problem that comes with it is its safety. What everyone is most concerned about with electric toothbrushes must be its waterproof performance and overall sealing performance. The most direct one is that if the airtightness and waterproofness of the toothbrush is not enough, it will lead to a series of safety issues such as leakage or greatly shortened service life, which will reduce the consumer experience.This is extremely detrimental to both electric toothbrush manufacturers and us consumers.Therefore, it is particularly important to test the IP66, IP67 or higher waterproof level of electric toothbrushes.So how do some electric toothbrush manufacturers carry out inspections on electric toothbrushes?Air tightness testingWoolen cloth?

Using ordinary methods to test will not only damage the product, but the accuracy will not meet the requirements. Products with slight leaks cannot be accurately identified and the efficiency is low. This requires the use of high-end and accurate testing methods as described in the following cases. Let's take a look.

The customer's requirements for the air tightness test of this electric toothbrush are: a test of positive pressure 45KPa, negative pressure -45KPa, program continuity and uninterrupted testing, and the sealing and waterproofing of the entire machine.It is required that the positive air inlet pressure does not exceed 45.6KPa and is not less than 45KPa, the negative pressure pressure does not exceed 46.1KPa and is not less than 45.5KPa, and its leakage value does not exceed 0.2KPa.

The difficulty in testing its waterproof sealing performance is that first of all, the machining accuracy of the mold cavity and toothbrush shape ratio is 1:1; the test accuracy requirements are higher, the sensor accuracy is 0.2% F.S, and the maximum effective fraction ratio is better than±1pa;Use AI algorithm to analyze the effective data of sample information, and automatically determine and identify the critical point of leakage.

We use the indirect test method to test this electric toothbrush. As shown in the picture above, we make a sealed cavity that is the same size as the product shape and specifications, that is, a mold. Try to fit the product as much as possible, because the test results will be more accurate. Then we pressurize the gas, and the gas will fill the space between the product and the mold. Then we cut off the air source and detect whether the gas pressure has dropped. If there is a leak, the gas has leaked into the product. If there is no drop, the test result means there is no problem.

The customer's demand is relatively large and they hope to detect defective products efficiently, so this four-channel fuel tank cap was customized for the customer.Air tightness testing equipment, can detect four products at the same time, and the test results are detected separately at the same time. The test results are accurate and are not affected by the other party's test results.It saves human resources and costs for customers.

For more than ten years, Hairuis has relied on its increasingly rich experience to provide customers with valuable sealing advice, supporting key materials or testing resources in the design, trial production, mass production and other stages, allowing customers to shorten the verification cycle and avoid detours; provide fast, high-quality one-stop service delivery according to customer requirementsAs well as some humanized function customization, as well as 24-hour and 8-hour efficient after-sales service outside the province, they have been unanimously recognized by customers; Hairuisi's products serve many companies domestically and are also exported to more than 50 countries overseas, and have achieved excellent reputation in all walks of life.
