This is a desktop garbage can, which is placed on the desktop to collect garbage. The garbage can be thrown in with a light push of your hand. The lid will automatically bounce back to prevent peculiar smell from overflowing. At the other end is a design point. For smokers, it can be a soot tank. For non-smokers, it can be used as a place for sorting dry and wet garbage. This slot is also easy to take and clean.
Then there is a design before optimization, and my friends can also leave a message to tell me which design is better.
