Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaners, and in particular to an opening structure of a dust cup. Background Art

[0002] Vacuum cleaners are a type of cleaning device widely used in daily life and industrial production. They operate by using an electric motor to drive the blades to rotate at high speed, creating negative air pressure within a sealed housing. This pressure then draws in dust through an external suction pipe. The dust cup is a key component of a vacuum cleaner, collecting trash and debris sucked in by the cleaner.

[0003] The existing dust cup unlocking mechanism of the vacuum cleaner usually simply releases the locked state of the dust cup, allowing the dust cup to be opened to empty the dust, but cannot effectively control the rotation opening angle of the dust cup after it is unlocked, making the dust cup opening method single and inconvenient to empty the dust cup. Summary of the Invention

[0004] The purpose of the present invention is to provide an opening structure of a dust cup, which can control the rotational opening angle of the dust cup after it is unlocked, so that the dust cup can have different opening angles according to needs.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a dust cup opening structure, comprising:

[0006] Dust cup holder;

[0007] The dust cup is rotatably mounted on the dust cup seat. A guide track is provided on the side wall of the dust cup. The guide track is arc-shaped and a buckle is provided at one end of the guide track.

[0008] A locking bracket, which is fixedly mounted on the vacuum cleaner body;

[0009] A lock member is rotatably mounted on the lock bracket, a first rotating shaft is provided on the lock member, and the lock member is rotatably mounted on the lock bracket via the first rotating shaft, a first torsion spring is sleeved on the first rotating shaft, and a hook is provided on the lock member, the position of which corresponds to the guide rail, and the hook is slidably connected to the guide rail;

[0010] A release push rod is slidably connected to the vacuum cleaner body, and a baffle is provided on the locking member, the position of which corresponds to the release push rod.

[0011] As a further description of the above technical solution:

[0012] Symmetrically arranged guide rails are provided on both sides of the dust cup.

[0013] As a further description of the above technical solution:

[0014] A second rotating shaft is provided at the bottom of the dust cup, and the dust cup is rotatably mounted on the dust cup seat through the second rotating shaft.

[0015] As a further description of the above technical solution:

[0016] A connecting block is provided at the bottom of the dust cup, and at least one second torsion spring is sleeved on the second rotating shaft. One torsion arm of the second torsion spring is inserted into the connecting block, and the other torsion arm is inserted into the dust cup seat.

[0017] As a further description of the above technical solution:

[0018] The second rotating shaft is provided with two second torsion springs.

[0019] As a further description of the above technical solution:

[0020] The two second torsion springs are symmetrically arranged on both sides of the connecting block.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. In the present invention, when the dust cup is unlocked, the release push rod on the vacuum cleaner body is pushed, and the release push rod moves along its own axis, squeezing the baffle of the lock member. Since the lock bracket remains in the same position, the lock member rotates relative to the lock bracket. At this time, the first torsion spring on the first rotating shaft of the lock member deforms and accumulates force, and the hook of the lock member disengages from the buckle position of the guide track on the dust cup, releasing the lock of the dust cup. The open end of the dust cup rotates downward and opens. The lock member controls the opening angle under the torsion of the first torsion spring, so that the hook fits the dust cup and slides along the guide track on the dust cup until the hook slides to one end of the guide track, completing the first stage of opening of the dust cup, that is, the first opening angle. The hook hooks the dust cup and controls the opening angle of the dust cup.

[0023] 2. In the present invention, if you want to further increase the opening angle of the dust cup, you can continue to push the release push rod to make the locking part rotate further, so that the hook at the bottom of it retreats and disengages from the guide track, and no longer hooks the dust cup, thereby realizing the second-stage opening of the dust cup, that is, the second opening angle, and the dust cup is fully opened.

[0024] 3. In this invention, to ensure smooth opening of the dust cup after unlocking, a second torsion spring is installed at the hinged connection between the dust cup and the dust cup holder. In the normal locked state, when the dust cup is horizontal, the second torsion spring is stretched and deformed, storing force. When the push rod is released to squeeze the locking element and unlock the dust cup, the dust cup rotates open under the elastic force of the second torsion spring. Conversely, when the dust cup is reset, it rotates back to its original position, stretching and deforming the second torsion spring, storing force. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0035] See also Figure 1-5The present invention provides a technical solution: an opening structure of a dust cup, comprising:

[0036] Dust cup holder 1;

[0037] The dust cup 2 is rotatably mounted on the dust cup seat 1. A guide track 21 is provided on the side wall of the dust cup 2. The guide track 21 is arc-shaped, and a buckle 211 is provided at one end of the guide track 21.

[0038] A locking bracket 3, which is fixedly mounted on the vacuum cleaner body;

[0039] The latch member 4 is rotatably mounted on the latch bracket 3. The latch member 4 is provided with a first rotating shaft 41. The latch member 4 is rotatably mounted on the latch bracket 3 via the first rotating shaft 41. A first torsion spring 42 is sleeved on the first rotating shaft 41. The latch member 4 is provided with a hook 44 whose position corresponds to the guide rail 21. The hook 44 is slidably connected to the guide rail 21.

[0040] The release push rod 5 is slidably connected to the vacuum cleaner body, and the locking member 4 is provided with a baffle 43 whose position corresponds to the release push rod 5.

[0041] Symmetrically arranged guide rails 21 are provided on both sides of the dust cup 2. Correspondingly, hooks 44 are provided on both sides of the locking member 4. The locking member 4 effectively limits the stability of the dust cup 2 when it is opened, prevents the dust cup 2 from deflecting left and right, and allows the dust cup to rotate smoothly and not easily deformed.

[0042] A second rotating shaft 22 is provided at the bottom of the dust cup 2, and the dust cup 2 is rotatably mounted on the dust cup seat 1 via the second rotating shaft 22. A connecting block 23 is provided at the bottom of the dust cup 2, and at least one second torsion spring 24 is sleeved on the second rotating shaft 22. One torsion arm of the second torsion spring 24 is inserted into the connecting block 23, and the other torsion arm is inserted into the dust cup seat 1. The dust cup 2 can be rotated and opened under gravity or the torsion force of the second torsion spring. In order to ensure that the dust cup 2 opens smoothly after being unlocked, a second torsion spring 24 is provided at the hinge between the dust cup 2 and the dust cup seat 1. In the normal locking state, when the dust cup 2 is in a horizontal state, the second torsion spring 24 is stretched and deformed, and accumulates force; when the push rod 5 is released to squeeze the locking member 4 and the dust cup 2 is unlocked, the dust cup 2 rotates and opens under the elastic force of the second torsion spring 24. Conversely, when the dust cup 2 is reset, the dust cup 2 rotates back to its original position, stretching and deforming the second torsion spring 24, and accumulating force.

[0043] The second rotating shaft 22 is provided with two second torsion springs 24 , which are symmetrically arranged on both sides of the connecting block 23 to ensure that the dust cup opens smoothly.

[0044] Working principle: The dust cup seat 1 is set on the vacuum cleaner body, and dust is collected in the dust cup 2. In the normal locking state, the hook 44 of the lock member 4 is stuck in the buckle position 211 of the side guide track 21 of the dust cup 2, and the dust cup 2 is in a horizontal state.

[0045] When the dust cup is unlocked, the release push rod 5 on the vacuum cleaner body is pushed, and the release push rod 5 moves along its own axis, squeezing the baffle 43 of the lock member 4. Since the lock bracket 3 remains in position, the lock member 4 rotates relative to the lock bracket 3. At this time, the first torsion spring 42 on the first rotating shaft 41 of the lock member 4 deforms and accumulates force, and the hook 44 of the lock member 4 disengages from the buckle position 211 of the guide track 21 on the dust cup 2, releasing the lock of the dust cup 2. The open end of the dust cup 2 rotates downward and opens. The lock member 4 controls the opening angle under the torsion of the first torsion spring 42, so that the hook 44 fits the dust cup 2 and slides along the guide track 21 on the dust cup 2 until the hook 44 slides to one end of the guide track 21, completing the first stage of opening of the dust cup 2, that is, the first opening angle. The hook 44 hooks the dust cup 2 and controls the opening angle of the dust cup 2.

[0046] If you want to further increase the opening angle of the dust cup 2, you can continue to push the release push rod 5 to make the locking part 4 rotate further, so that the hook 44 at its bottom retreats and disengages from the guide track 21, and no longer hooks the dust cup 2, thereby realizing the second-stage opening of the dust cup, that is, the second opening angle, and the dust cup is fully opened.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
