For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0023] Example: Figure 1-3 As shown, the utility model discloses an embodiment of a dust cup of a vacuum cleaner, which includes: a cup body 100 having a primary cyclone chamber 120 and a primary dust collecting chamber 140 therein, a filter screen cover 200 disposed in the primary cyclone chamber 120 and having a mesh portion 220, a cyclone assembly 300 located downstream of the mesh portion 220 and at least partially surrounded by the mesh portion 220, a dust cup cover 400 for shielding the bottom of the primary dust collecting chamber 140, a plug 500 detachably mounted on one end of the secondary dust collecting chamber 340 and used to separate the primary dust collecting chamber 140 from the secondary dust collecting chamber 340, a pushing block 600 disposed on one side outside the cup body 100 and driving the action block 260 of the filter screen cover 200 to move, a first elastic member 620 supporting the pushing block 600, and a second elastic member 640 disposed on the other side inside the cup body 100 and acting on the filter screen cover 200.

[0024] The cup body 100 is generally hollow cylindrical, and includes a pivot end 160 disposed at one end, and a bottom cover button 180 disposed at the other end, wherein one end of the dust cup cover 400 rotates around the pivot end 160 and the other end is provided with a bottom cover lock 420 that locks with the bottom cover button 180.

[0025] The filter screen cover 200 includes a front filter 240 disposed at the top of the mesh part 220 and located downstream, and an action block 260 that can push the filter screen cover 200 to move in the axial direction and is disposed on one side of the mesh part 220. The front filter 240 is a hepa or sponge. The mesh part 220 is provided with a plurality of meshes 222 to prevent large particles of dust from entering the meshes 222 and flowing into the cyclone assembly 300.

[0026] The cyclone assembly 300 is fixedly arranged in the filter screen cover 200, and includes a secondary cyclone 320 for generating a secondary cyclone, a secondary dust collecting chamber 340 located at the bottom of the secondary cyclone 320, and an air guide 360 ​​for guiding the airflow after the secondary cyclone. There are multiple secondary cyclones 320, and they share a secondary dust collecting chamber 340. The secondary cyclone 280 is roughly in the shape of a truncated cone, with a larger upper end and a smaller lower end. The air guide 360 ​​is arranged at the center of the secondary cyclone 320 and above the secondary dust collecting chamber 340, and is located upstream of the front filter element 240. The airflow enters from the air inlet of the cup body 100, and performs a primary cyclone in the primary cyclone chamber 120. Under the action of centrifugal force, large dust particles fall into the bottom of the primary dust collecting chamber 140, and then fall onto the dust cup cover 400. When the user presses the bottom cover button 18, one end of the dust cup cover 400 rotates around the pivot end 160 to open the bottom of the primary dust collecting chamber 140, thereby emptying the dust. After the fine dust airflow passes through the mesh 222 upward, it enters the inlet of the secondary cyclone 320, and performs a secondary cyclone in the secondary cyclone 320. Under the action of centrifugal force, the fine dust falls into the bottom of the secondary dust collecting chamber 340 and falls onto the plug 500. Then the airflow filtered by the fine dust enters the front filter 240 from the air guide 360 ​​for further filtration, and finally flows to the vacuum motor.

[0027] The dust cup cover 400 is provided with a bottom cover recessed portion 440 located below the primary dust collecting chamber 140 and arranged corresponding to the plug 500. The bottom cover recessed portion 440 is used to collect dust in the primary dust collecting chamber 140.

[0028] The plug 500 is made of soft rubber material, and is sealed with the outer wall or the inner wall of the secondary dust collecting chamber 340 , and is fixed by the elasticity of its own material.

[0029] The push block 600 reciprocates along the axial direction of the cup body 100 and is driven upward or downward by the user's finger, so that the filter screen 200 moves along the axial direction and can scrape the inner wall of the cup body 100 to clean the dust attached to the surface of the mesh 222, reduce mesh blockage, and ensure work reliability. The first elastic member 620 and the second elastic member 640 have opposite action directions, and are preferably compression springs.

[0030] Therefore, the utility model adds a plug, and the dust in the secondary dust collecting chamber can be cleaned by opening the plug, which is convenient for cleaning, has a reliable structure and lowers the cost, and improves the consumer's use experience.

[0031] The advantages of the utility model are: to achieve mutual isolation between the primary dust collecting chamber and the secondary dust collecting chamber to avoid airflow crosstalk, and at the same time facilitate users to clean the dust in the secondary dust collecting chamber to ensure reliable operation; when the user opens the plug when cleaning the secondary cyclone regularly, the dust in the secondary cyclone will fall to the bottom of the secondary dust collecting chamber, avoiding users from disassembling the secondary cyclone and improving the user experience.

[0032] The above are only preferred implementations of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present utility model, which should be included in the protection scope of the present utility model.
