Description

Technical Field

[0001] This utility model relates to the field of dust collection base station technology, and in particular to a structure based on negative pressure driving the dust cup lid to open. Background Technology

[0002] During the use of dust collection base stations and dust cups, the opening and closing of the dust cup lid directly affects dust collection efficiency, ease of operation, and sealing. Existing technologies for unlocking dust cup lids often have the following shortcomings:

[0003] Manual unlocking is cumbersome, especially since dust may adhere to the dust cup after dust collection, and manual contact can easily cause contamination. Some automatic unlocking structures use motors to directly drive mechanical components (such as push rods and connecting rods), which not only have complex structures and a large number of parts, but are also prone to shortened lifespan due to mechanical wear. Furthermore, the high precision required for the fit between the drive components and the dust cup increases production and maintenance costs. Existing drive methods (such as direct motor drive) do not work in synergy with the negative pressure dust collection function of the dust collection base station, resulting in low utilization of internal space and redundant functional modules.

[0004] Therefore, there is an urgent need for an automatic unlocking structure for the dust cup lid that is simple in structure, reliable in drive, and can work in conjunction with the dust collection negative pressure system to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, such as cumbersome operation, complex structure and insufficient functional coordination of dust cup lid unlocking, and to provide a structure based on negative pressure to drive the dust cup lid to open, so as to realize the automatic unlocking and opening of the dust cup lid, simplify the structure, reduce costs, improve the convenience of operation and dust collection sealing.

[0009] A negative pressure unit, the negative pressure end of which is connected to the channel;

[0010] In the unlocked state, the negative pressure unit creates negative pressure in the negative pressure chamber through the channel and drives the actuator to rotate, thereby causing the actuator end to extend out of the mounting chamber and triggering the dust cup lid locking mechanism to unlock.

[0011] The preferred technical solution is as follows: the actuator is composed of a rotating shaft, a wing plate, and a top plate. The rotating shaft is rotatably connected to the installation chamber. The top plate is configured to extend out of the installation chamber and correspond to the dust cup cap locking mechanism. A gap is left between the end of the wing plate and the inner wall of the negative pressure chamber. An air inlet is provided on the bottom side of the installation chamber to communicate with the outside.

[0012] The preferred technical solution is that the channel is located on the rotating shaft.

[0013] The preferred technical solution is that the channel is located on the installation compartment.

The locking tongue end of the unlocking component is correspondingly arranged with the latch.

[0017] The preferred technical solution is as follows: the dust collection base station is provided with a dust collection chamber, the opening of the dust collection chamber is correspondingly arranged with the cup lid, and the dust collection chamber is provided with a cup lid pressing mechanism for pressing the cup lid to lock with the dust cup lid locking mechanism.

[0036] Example:

[0037] like Figures 1 to 7 As shown, according to a general technical concept of this utility model, a structure for opening a dust cup lid based on negative pressure is provided, comprising:

[0038] Installation compartment 1;

[0039] Actuator 2 is installed in installation chamber 1, and its actuating end is configured to extend out of installation chamber 1 and be correspondingly set with dust cup lid locking mechanism 3; the interior of installation chamber 1 forms negative pressure chamber 4, and a channel 5 communicating with negative pressure chamber 4 is provided on actuator 2 or installation chamber 1;

[0040] Negative pressure unit 6, whose negative pressure end is connected to channel 5;

[0041] In the unlocked state, the negative pressure unit 6 creates negative pressure in the negative pressure chamber 4 through the channel 5 and drives the actuator 2 to rotate, thereby causing the actuator end of the actuator 2 to extend out of the installation chamber 1 and actuate the dust cup lid locking mechanism 3 to unlock.

[0042] like Figures 1 to 7 As shown, in an exemplary embodiment of this utility model, the actuator 2 consists of a rotating shaft 21, a wing plate 22, and a top plate 23 (i.e., the actuating end). The rotating shaft 21 is rotatably connected to the mounting chamber 1. The top plate 23 is configured to extend out of the mounting chamber 1 and correspond to the dust cup lid locking mechanism 3. A gap is left between the end of the wing plate 22 and the inner wall of the negative pressure chamber 4. The bottom side of the mounting chamber 1 is provided with an air inlet that communicates with the outside. During operation, the negative pressure unit 6 forms a negative pressure in the negative pressure chamber 4 through the channel 5. The airflow flows sequentially through the air inlet and the channel 5. Under the action of the airflow, the wing plate 22 is subjected to force, which drives the rotating shaft to rotate, and at the same time drives the top plate 23 to push out and unlock. After unlocking, at the moment the dust cup lid is opened, the air pressure in the negative pressure chamber 4 decreases, and the force of the airflow acting on the wing plate 22 is less than the weight of the wing plate 22, so the wing plate 22 automatically resets.

The inner side of the unlocking end of the unlocking member 31 is connected to the cup body 81 by the spring 32. The locking tongue end of the unlocking member 31 is correspondingly arranged with the locking buckle 821.

[0048] like Figures 1 to 7 As shown, in an exemplary embodiment of this utility model, the dust collection base station 7 is provided with a dust collection chamber 72, the opening of the dust collection chamber 72 is correspondingly arranged with the cup lid 82, and the dust collection chamber 72 is provided with a cup lid pressing mechanism 9, which is used to press the cup lid 82 to form a lock with the dust cup lid locking mechanism 3.

[0049] like Figures 1 to 7 As shown, in an exemplary embodiment of this utility model, the cup lid pressing mechanism 9 consists of a motor 91, a gear 92, an arc-shaped rack 93, and a chamber lid 94; the motor 91 is fixed inside the dust collection base station 7 and is used to drive the gear 92 to rotate; the chamber lid 94 is correspondingly matched with the opening of the dust collection chamber 72, and one end is rotatably connected to the opening of the dust collection chamber 72; the arc-shaped rack 93 is fixed on the inner side of the chamber lid 94 and meshes with the gear 92; the motor 91 drives the chamber lid 94 to flip through the gear 92 and the arc-shaped rack 93 to press the cup lid 82 to lock with the dust cup lid locking mechanism 3.

[0050] like Figures 1 to 7 As shown, in an exemplary embodiment of this utility model, the negative pressure unit 6 is a vacuum motor and is located in the dust collection base station 7; the negative pressure end of the negative pressure unit 6 is also connected to the dust collection chamber 72, that is, it is used to suck the garbage in the dust cup 8 into the dust collection chamber 72.

[0051] Therefore, this utility model has the following advantages:
