Why some aligner ultrasonic pod failed after few months working?
On amazon or some ultrasonic pod selling website, you will find some comments that some of mini ultrasonic pods failure working after it works a few months. Do you know why those ultrasonic pods failure working?And how to avoid this problem happend ? How to choose a good ultrasonic pod with strong cleaning and durable lifespan? As a ultrasonic cleaner manufacturer 10+ years, engineers with 20+years experience on ultrasonic cleaners, we share some reasons and points for you.

If you check on amaon, ebay or other e-commerce platform, you will find some user comments that some ultrasonic pod failure working after it work 2-4 months. However, by the external looking, the aligner ultrasonic pod is still good looking, and it just can't clean anyway. Do you know why? And how to avoid this happen? If you are a distribtor or brands for mini ultrasonic pod https://bestsonicbath.com/products/bestsonicbath-aligner-invisalign-dental-ultrasound-cleaner-pod-28w-with-uvc-sterilization-mini-tank-250ml , you must want to know if the ultrasonic pod manufacturer is professional or not, how they work to ensure stable quality for the ultrasonic pod. Why some have ultrasonic cleaner pods are failire within 5 months, while others' not? As a ultrasonic cleaner factory who specialzed in producing ultrasonic cleaners more than 10 years, and engineers with 20 years of ultrasonic cleaner pod experience, we like to share some reasons and suggests for choosing a good ultrasonic cleaning pod.
Here are some reasons making aligner ultrasonic pod failure working within few months:1. Using low quality ultrasonic piezo or ultrasonic piezo installing not stable. 1.1. Ultrasonic piezo is the main part for the ultrasonic cleaner pod, it decides ultrasonic cleaning power. If using low quality ultrasoinic piezo it will only work several months, then it stop vibrating. 1.2. Using low quality heat conducting glue/gel. The ultrasonic piezo need to use the glue/ gel to stick the ultrasonic piezo on the tank. The gel/glue is heat deducting, it will stick well even ultrasonic piezo is with high temperature for long time vibrating. But if using low quality glue, it can't stick well. The piezo will loose after several months vibration. 1.3. The copper cable is soldered not durable. If the copper cable soldered not well, it can work at first a few months. After ultrasonic piezo vibrates long time, the temperature inside is hot and loose. Because the soldering cable was fake soldering in previously, it just sticked a little. After long time working, when temperature heat up, the cable will loose. The cable loose and the ultrasonic piezo can't work. By above mentioning problems, can they be avoided? The answer is YES.
How to make aligner ultrasonic pod quality stable and lifespan durable? Here are some suggestions: 1. To use top quality ultrasonic piezo. 2. To use top pcb circuit board for the mini ultrasonic pod. If using low quality circuit board, it might happen below several situations, and making ultrasonic pod failure:2.1 Using bad circuit board, will make heat conducting not well. After long time working, the heat on circuit board, will make circuit board burnt.2.2. The design on pcb if not well, will make current on circuit board too high, will make pcb burnt easily.2.3. If the circuit board without overload for current and voltage or over temperature protection, the aligner ultrasonic cleaner pod will also be burnted after long time working.So above points are all happen if using low quality circuit board. However, in the market, if there is not circuit board burnt for too high temperature, it doesn't mean that circuit board is good quality. Because one very easy and low cost way to make low temperature on circuit board is to make circut board power small. As long as the the power is small, no ultrasonic pod will be damaged for too high temperature. But low power always be with weak ultrasonic cleaning. Weak cleaning is with very little cleaning effect. So low temperature doesn't mean that is a good ultrasonic cleaning pod. In the amazon or tiktok e-commerce platform, you will find there always suggesting tablets with ultrasonic pod together. That is because weak cleaning of the ultrasonic pod, so they suggest always with tablets.
A good ultrasonic pod is with strong cleaning power, and only needs tablets for first 7-10days to clean away its stinky smell from the aligner, denture. In daily cleaning, the good ultrasonic pod https://bestsonicbath.com/products/bestsonicbath-aligner-invisalign-dental-ultrasound-cleaner-pod-28w-with-uvc-sterilization-mini-tank-250mlcan clean the aligners, dentures, mouthguard well only by tap water. The good ultrasonic pod should be with overheat protection. So when ultrasonic piezo works very long time, it will activate the overheat protection. Users just wait for 15-20minutes for ultrasonic pod cooling ,then it will ultrasonic cleaning again.
