Description
Technical Field
[0001] The utility model relates to the field of vacuum cleaners, in particular to a dust cup mounting structure. Background Art
[0002] In the field of vacuum cleaners and similar cleaning devices, the dust cup is a key component for collecting dust and debris. The stability and ease of use of its assembly structure directly affect the user experience and the overall performance of the device. Currently, one of the widely used dust cup assembly methods for handheld vacuum cleaners on the market is a rotary assembly locking structure. In this structure, the dust cup is rotated to cooperate with and lock to the interface part on the device main body to achieve the fixed installation of the dust cup. However, the dust cup assembled by rotation has always had the problem that it is difficult to control the tightness feeling. Due to factors such as the dust cup material, dimensional tolerance, and deformation during long-term use, it is often difficult to precisely control the tightness during rotary assembly. If it is too tight, it may cause difficulties for users to assemble, and even damage the dust cup or the device main body; if it is too loose, it may lead to poor sealing, affecting the dust suction effect and dust leakage. Content of the Utility Model
[0003] The purpose of the utility model is to solve the above technical problems and provide a dust cup mounting structure. This application aims to provide a plug-in mounting dust cup mounting structure.
[0004] A dust cup mounting structure includes a mounting main body and a dust cup. The mounting main body includes a first mounting part and a second mounting part arranged at an angle to each other. A mounting position for the dust cup is formed in the area sandwiched by the first mounting part and the second mounting part.

The shape of the fulcrum groove matches the shape of the fulcrum. The structure of the arc surface enables the dust cup to produce a slight upward lifting effect on the dust cup when it is inserted along the arc surface, so as to clamp the dust cup with the first installation part.
[0010] Still further, an electrode sheet is provided on the side of the fulcrum of the first installation part, and an electrode contact is provided on the side of the fulcrum groove of the dust cup. When the dust cup is installed on the installation main body, the electrode sheet and the electrode contact are in mutual contact.
