[0002] A vacuum cleaner is a common household cleaning device, which mainly includes a main unit, a dust cup, and a suction tube. The dust cup is used to collect dust and debris sucked in during the cleaning process. After a certain period of use, the dust and debris inside need to be poured out. Therefore, the dust cup is usually detachably set on the main unit, and the dust cup and the main unit are connected by a locking structure. In order to reduce the frequency of cleaning the dust cup, some vacuum cleaner products on the market are designed with a relatively large dust cup volume based on user experience requirements, resulting in a decrease in dust collection efficiency.

[0004] The above-mentioned prior art is to install the dust cup close to the handle. When the user holds the handle, he or she uses the index finger to push the release button to push the release push rod. When the release push rod moves downward, it is inserted between the lock buckle and the buckle position. The user needs to exert a large force to drive the release button. In particular, when the user holds the palm of the hand on the handle and extends the index finger alone to operate the release button, it is difficult for the finger to exert force, and it is easy for the user to lose the grip of the handle, making it difficult to operate.

[0005] Therefore, the prior art still needs to be improved and developed. Utility Model Content
