[0029] Please see Figures 1-4

[0030] Example 1: An opening and closing structure for a dust cup lock of a handheld vacuum cleaner includes a dust cup cover assembly 1, a dust cup body 4 disposed below the dust cup cover assembly 1, a torsion spring body 2 disposed between the dust cup cover assembly 1 and the dust cup body 4, a rotating shaft body 3 disposed on the torsion spring body 2, a push button body 5 disposed on the side of the dust cup body 4, a spring body 6 disposed on the push button body 5, a button body 7 disposed on the side of the dust cup body 4, and a bottom filter assembly 8 disposed at the bottom of the dust cup cover assembly 1.

[0031] The dust cup top cover assembly 1 has a dust cup locking position 101 on the side of its bottom, a torsion spring mounting hole 102 on the other side of its bottom, a top cover torsion spring slot 103 on the side of the torsion spring mounting hole 102, and a top cover rotating shaft mounting post 105 at the bottom of the dust cup top cover assembly 1. A top cover rotating shaft mounting hole 104 is opened in the middle of the top cover rotating shaft mounting post 105.

[0032] A left torsion spring limiting arm 201 is provided on one side of the torsion spring body 2, and a right torsion spring limiting arm 202 is provided on the other side of the torsion spring body 2.

[0033] A button mounting groove 401 is provided on the side of the top of the dust cup body 4. A button limiting clearance 402 is provided on the side of the button mounting groove 401. A dust cup limiting plane 403 is provided on the side of the button limiting clearance 402. A dust cup torsion spring groove 404 is provided on the other side of the top of the dust cup body 4. A top cover pivot mounting groove 406 is provided on the side of the dust cup torsion spring groove 404. Two dust cup pivot mounting holes 405 are symmetrically provided on both sides of the inner wall of the top cover pivot mounting groove 406. A filter component mounting hole 407 is provided at the bottom of the dust cup body 4.

[0034] The front of the push key body 5 is provided with a push key lever 501, the back of the push key body 5 is provided with a push key limiting boss 502, the side of the push key limiting boss 502 is provided with a push key mounting surface 503, and the side of the back of the push key body 5 is provided with a push key limiting surface 504.

[0035] Example 2: The difference between this example and Example 1 is that the button body 7 has a button latch 701 on its side, two button limiting posts 702 symmetrically arranged on the bottom side of the button latch 701, a button mounting post 703 on the side of the button body 7, a button mounting hole 704 on the side of the button body 7, a push button latch 705 installed in the button mounting hole 704, a button groove 706 below the button mounting hole 704, an upper push button limiting groove 707 on the inner wall of the button body 7, a lower push button limiting groove 708 on the side of the upper push button limiting groove 707, and a spring mounting post 709 on the side of the button limiting post 702.

[0036] Example 3: The difference between this example and Example 1 is that the top of the dust cup cover assembly 1 is provided with an inclined opening.

[0037] This makes it easier to suck up dust from the dust cup cover assembly 1.

[0038] Example 4: The difference between this example and Example 1 is that the side of the button body 7 is grooved.

[0039] This allows the button body 7 to be more appropriately inserted into the button assembly slot 401.

[0040] In this embodiment, since handheld vacuum cleaners on the market are generally bulky, the lock is easily accidentally touched, which can lead to the cup lid being opened by mistake, resulting in a poor user experience and inconvenience for users.

[0041] In summary, during implementation, the user first needs to assemble the device. The user first passes the push-button lever 501 of the push-button body 5 through the button mounting hole 704 of the button body 7, and the push-button mounting plane 503 of the push-button body 5 is fastened to the push-button buckle 705 of the button body 7. The spring body 6 is then assembled onto the spring mounting post 709 of the button body 7, and the push-button limiting boss 502 of the push-button body 5 is assembled onto the push-button limiting groove 707 of the button body 7, thus assembling the button assembly.

[0042] The assembled button assembly is assembled into the dust cup body 4. The button assembly post 703 of the button body 7 is assembled into the button assembly slot 401 of the dust cup body 4. The spring body 6 maintains the spring pressure on the dust cup limiting plane 403 of the dust cup body 4. The assembly forms the dust cup body assembly. Under the action of the spring, the button assembly will always remain in a locked state. In order to keep the button assembly in a locked state, the button limiting post 702 of the button body 7 pushes against the dust cup limiting plane 403 of the dust cup body 4.

[0043] The torsion spring body 2 is assembled into the torsion spring mounting hole 102 of the dust cup top cover assembly 1, so that the left 201 of the torsion spring limiting arm of the torsion spring body 2 is assembled into the top cover torsion spring slot 103 of the dust cup top cover assembly 1.

[0044] The upper cover shaft mounting post 105 of the dust cup upper cover assembly 1 is mounted to the upper cover shaft mounting groove 406 of the dust cup body 4, so that the torsion spring mounting hole 102 of the torsion spring body 2 is mounted into the dust cup torsion spring groove 404 of the dust cup body 4, and the shaft body 3 passes through the upper cover shaft mounting hole 104 of the dust cup upper cover assembly 1 and the torsion spring limiting arm right 202 of the torsion spring body 2 and is mounted onto the dust cup shaft mounting hole 405 of the dust cup body 4.

[0045] Next, assemble the bottom filter assembly 8 onto the filter assembly assembly hole 407 of the dust cup body 4. Due to the force of the torsion spring body 2, the dust cup top cover assembly 1 will remain open. Close the dust cup top cover assembly 1 so that the dust cup locking position 101 of the dust cup top cover assembly 1 is engaged with the button locking position 701 of the button body 7. Move the push button lever 501 of the push button body 5 downward so that the push button limiting protrusion 502 of the push button body 5 moves into the push button limiting groove 708 of the button body 7. At this time, the dust cup top cover assembly 1 and the dust cup body 4 are locked. In the locked state, the push button limiting plane 504 of the push button body 5 presses against the dust cup limiting plane 403 of the dust cup body 4. At this time, the button groove 706 of the button body 7 cannot be pressed, so the lock cannot be opened, thus preventing accidental touch that would open the dust cup top cover assembly 1.

[0046] When opening the device, the user can push the push button lever 501 of the push button body 5 upwards, causing the push button limiting boss 502 of the push button body 5 to move onto the push button limiting groove 707. The push button limiting plane 504 of the push button body 5 then leaves the dust cup limiting plane 403 of the dust cup body 4 and reaches the button limiting clearance 402 of the dust cup body 4. Pressing the button groove 706 of the button body 7 causes the button latch 701 of the button body 7 to rotate around the center of the button mounting post 703 of the button body 7. The button latch 701 of the button body 7 disengages from the dust cup locking latch 101 of the dust cup top cover assembly 1. Under the force of the spring body 6, the dust cup top cover assembly 1 will automatically open.

[0047] This design makes the device lighter and more aesthetically pleasing, and prevents accidental opening of the latch, greatly improving the user experience and making it more convenient for users.
