The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The embodiment discloses a dust cup cover one-key opening assembly and a dust collector comprising the same. As shown in fig. 1 to 3, the one-key opening assembly of the dust cup cover comprises a dust cup, a push button 1, a guide rod 2, a push block 3 and an elastic member capable of resetting the push block 3, wherein the dust cup comprises a dust cup body 9 and a dust cup cover 5, and the push button 1 is arranged on a handle 11 or at a position close to the handle 11 so as to facilitate a user to press and push the push button 1; the push button 1 is connected with the guide rod 2, and the guide rod 2 can be abutted against the push block 3 when moving forwards. The push block 3 is provided with two first pushing parts 31 for pushing the elastic arm 51 of the hook 4 or the dust cup cover 5, the two first pushing parts 31 are respectively positioned at two sides of the guide rod 2, and the push block 3 opens the dust cup cover 5 by pushing the elastic arm 51 of the hook 4 or the dust cup cover 5.

The push block 3 of the dust cup cover one-key opening assembly is provided with two first push-press parts 31 for opening the dust cup cover 5, the two first push-press parts 31 are symmetrically arranged on two sides of the guide rod 2, when the guide rod 2 moves forwards, the push block 3 also moves forwards, the two first push-press parts 31 apply force from two sides to push the dust cup cover 5 to unlock, the problem that a lock catch and a groove are locked (locked) easily due to the fact that a thin rod is directly used for pushing the lock catch in the existing structure is solved, unlocking of the dust cup cover 5 is smoother, and labor is saved; the dust cup cover 5 can be opened by a single hand of a user, and dust and micro particles in the dust cup body 9 can be poured out without contacting the dust cup cover 5, so that the dust cup is clean and convenient.

In order to increase the stability when the guide rod 2 abuts against the push block 3, the push block 3 is preferably provided with a stress plate 32 protruding out of the surface, the stress plate 32 is of a planar structure with a large area, even if the guide rod 2 slightly moves in the radial direction when moving forwards, the stress plate 32 can be accurately abutted against the stress plate, the problem that point-to-point contact is easy to stagger mutually is solved, the phenomenon that the guide rod 2 passes through the push block 3 by rubbing against the shoulder when moving forwards is avoided, and the use is more convenient and labor-saving.

In order to avoid the pushing block 3 from moving forward too far under the pushing of the guide rod 2, and even the pushing block 3 flies out due to inertia forward due to the fact that the structure of the pushing block 3 which is not abutted to the first pushing part 31 is not abutted after the dust cup cover 5 is unlocked, the one-key opening assembly for the dust cup cover further comprises a pressing plate 6, and as shown in fig. 2 and 7, the pressing plate 6 is arranged above the pushing block 3, and a limiting groove 61 is formed in the pressing plate 6. The stress plate 32 reciprocates in the limiting groove 61, and when the stress plate 32 reaches the bottom edge of the limiting groove 61, the push block 3 cannot move forward continuously, so that the push block 3 is ensured to move in a set range all the time.

On the basis of the structure, as shown in fig. 2 and 8, the dust cup cover one-key opening assembly further comprises a guide block 7, the push block 3 is of a U-shaped structure, and the push block 3 is sleeved on the outer side of the guide block 7. Specifically, the pushing block 3 includes two first pushing parts 31 extending vertically downward and a connecting top surface connected between the two first pushing parts 31, and one first pushing part 31, the connecting top surface and the other first pushing part 31 are sequentially connected to form a U-shaped structure or an arch bridge-shaped structure. The push block 3 with a U-shaped structure can be spanned on the guide block 7, specifically, the connecting top surface is located above the guide block 7, and the two first pushing parts 31 are respectively located at two sides of the guide block 7.

After the installation, the pressing plate 6, the pushing block 3 and the guide block 7 are sequentially overlapped from top to bottom, and the pressing plate 6 and the guide block 7 jointly limit the pushing block 3 to move in four directions, namely up, down, left and right directions, so that the pushing block 3 can only move in the front-back direction. The stress plate 32 is a sheet surface protruding from the connecting top surface, the first pushing part 31 and the connecting top surface are integrated, when the guide rod 2 pushes the stress plate 32 forwards, a certain distance exists between the stress point on the stress plate 32 and the center of the connecting top surface, so that the whole push block 3 has the tendency that the front end is pressed downwards and the rear end is upwarped under the pushing force of the guide rod 2, and the push block 6 and the guide block 7 prevent the tilting tendency of the push block 3, so that the push block 3 can only move forwards smoothly, and the push block 3 is further prevented from being locked with the push block 6 or the guide block 7 in the moving process.

The specific structure of the guide block 7 is not limited, and a space capable of guiding and limiting the push block 3 can be formed together with the pressure plate 6, and the push block 3 can reciprocate in the limiting space but cannot move up and down. The guide block 7 may be a specially added structure, or an existing structure in the cleaner (e.g., a duct housing) may be used as the guide block 7. The air duct shell is preferably used as the guide block 7, the structure of the existing dust collector is not required to be changed too much, and the manufacturing cost is lower.

As shown in fig. 4 and 5, a gap Hj is provided between the push block 3 and the hook 4 or between the push block 3 and the elastic arm 51, so that once the push button 1 is accidentally touched, the push block 3 only moves forward by a distance and then is attached to the hook 4 or the elastic arm 51, and the dust cup cover 5 cannot be mistakenly opened by mistakenly pushing the hook 4 or the elastic arm 51. Can also set up suggestion structure on the mount pad that pushes away button 1, for example arch, damping member or elasticity protruding structure etc. the user can feel the existence of above-mentioned suggestion structure when the touch pushes away button 1, reminds the user through the suggestion structure that push away button 1 has got into effective displacement interval, will play dirt bowl cover 5 if continue to promote to push away button 1.

As shown in fig. 6, two elastic member mounting posts 33 are provided on the push block 3, and the two elastic member mounting posts 33 are respectively located on both sides of the guide bar 2. The elastic piece (such as a spring) can provide reset driving force for the push block 3, the push block 3 can automatically reset after a user releases the push button 1, the push block 3 does not need to be manually pulled back by the user, and the use is more convenient. Because the thrust of the elastic part acts on the plane of the elastic part mounting column 33, the thrust of the guide rod 2 is applied on the stress plate 32, and the plane of the elastic part mounting column 33 and the stress plate 32 are not on the same plane, the push block 3 tends to turn over under the resultant force of the two forces, and further the push block 3 needs to be limited by the pressure plate 6 and the guide block 7, so that the push block 3 can stably move forwards.

When the hook 4 is arranged between the pushing block 3 and the dust cup cover 5, the specific structure of the hook 4 is not limited, and the dust cup cover 5 can be stably locked and unlocked under the action of the pushing block 3. Preferably, as shown in fig. 9 and 10, the hook 4 includes a sleeve 41 with a through hole 45 therein, a second pushing portion 42 for abutting against the pushing block 3, a hook portion 43 for hooking on a cover body hook 52 of the dust cup cover 5, and an elastic rod 44 for driving the hook 4 to rotate and reset. The second pushing part 42, the hook 43 and the elastic rod 44 have one end provided on the cannula 41 and the other end extending outward in the radial direction of the cannula 41. The elastic rod 44 can be replaced by a torsion spring as long as the hook 4 can be driven to reset.

Two hooks 4 are arranged at positions corresponding to the two first pushing parts 31, a sleeve 41 of each hook 4 is sleeved on one rotating shaft 8, and the rotating shaft 8 is fixedly or pivotally connected to a mounting base (such as a shell of a dust collector). When the pushing block 3 moves forward, the first pushing part 31 abuts against the second pushing part 42 and pushes the second pushing part forward, the sleeve 41 rotates around the axis of the rotating shaft 8 or the sleeve 41 and the rotating shaft 8 rotate together around the axis of the rotating shaft 8, the hook part 43 rotates for a certain distance and then is separated from the cover body hook 52, and the dust cup cover 5 is automatically opened under the action of self weight or the action of a torsion spring at the hinged shaft.

Based on the above structure, preferably, the length Ht of the second pushing part 42 is smaller than the length Hg of the hook part 43, so that the user only needs to push the push button 1 forward by a small stroke (i.e. the second pushing part 42 rotates by a small angle around the axis of the through hole 45) to move the hook part 43 by a long arc, so as to disengage from the cover hook 52, thereby opening the dust cup cover 5 more conveniently and more labor-saving. The length Ht of the second pressing portion 42 is the distance from the tip of the second pressing portion 42 to the outer wall of the cannula 41, and the length Hg of the hook 43 is the distance from the tip of the hook 43 to the outer wall of the cannula 41.

On the basis of the structure, a knurling structure is formed on the guide rod 2, so that the guide rod 2 can be better occluded with the push block 3 positioned in front and the push button 1 positioned in rear respectively, and the three move synchronously.

When the dust collector is used, the motor of the dust collector is started, air flow carrying dust or tiny impurities enters the air channel from the air inlet, and is discharged from the air outlet 10 after passing through the dust cup and the motor. The filter means (e.g. HEPA) in the dirt cup 9 traps dirt and small impurities, ensuring that the air flow exiting the air outlet 10 is clean and avoiding contamination of the ambient air.

After a period of use, a certain amount of dust, tiny impurities and the like are accumulated in the dust cup body 9 and need to be removed. The user singlehanded promotion pushes away button 1 antedisplacement and sets for the distance, guide arm 2 is along with pushing away button 1 antedisplacement and promoting ejector pad 3 antedisplacement to setting for the position department, ejector pad 3 promotes the second portion 42 that bulldozes forward, couple 4 is whole rotatory around the axis of through-hole 45 because of the second portion 42 atress that bulldozes, hook 43 moves along the direction opposite with ejector pad 3 moving direction until thoroughly breaking away from mutually with lid hook 52, dirt cup lid 5 is opened, the user can empty dust and small impurity etc. in the dirt cup 9 in the garbage bin simply conveniently.
