Description

Technical Field

[0001] This utility model relates to a vacuum cleaner with an unlocking device. Background Technology

[0002] Vacuum cleaners typically include a dust cup with one end exposed and hollow, and a dust cup lid located at one end of the dust cup. The dust cup lid can be rotated open to empty the dust from the dust cup into a trash can. This type of technology can be referenced in Chinese invention patent CN107049138A.

[0024] Example: Figure 1-6 As shown, this utility model discloses a specific embodiment of a vacuum cleaner with an unlocking device, which includes: a vacuum cleaner housing 1000, a dust cup portion 2000 detachably connected to the vacuum cleaner housing 1000 and having a dust cup cover 2200 and a push rod 2600, a motor 3000 located inside the vacuum cleaner housing 1000 and generating a vacuum inside the dust cup portion 2000, a power supply 4000 supplying power to the motor 3000, and an unlocking device 5000 located between the vacuum cleaner housing 1000 and the dust cup portion 2000 and capable of causing the dust cup cover 2200 to rotate open.

[0025] The vacuum cleaner housing 1000 includes an air inlet pipe housing 1200 with an air inlet, a motor housing 1400 detachably connected to the dust cup portion 2000 and used to house the motor 3000, and a handle housing 1600 having one end connected to the air inlet pipe housing 1200 and the other end adjacent to the dust cup portion 2000 and having a grip portion 1620. The handle housing 1600 includes a switch 1624 located at the top for controlling the operation of the motor 3000, and a locking portion 1628 located at one end of the grip portion 1620 for securing one end of the dust cup portion 2000, wherein an unlocking device 5000 is located below the switch 1624.

[0026] The dust cup portion 2000 also includes a hollow dust cup cavity 2020, one end of which can be covered by a dust cup cover 2200; a mesh cover 2400 disposed within the dust cup cavity 2020; and a filter element 2460 located downstream of the mesh cover 2400 and upstream of the motor 3000. The dust cup cover 2200 includes a dust cup cover latch 2220 located at one end and locking with one end of a push rod 2600, and a dust cup cover pivot 2240 located at the other end; wherein the dust cup cover latch 2220 rotates about the pivot relative to the dust cup cover pivot 2240. The filter element 2460 is preferably a sponge or HEPA filter. The push rod 2600 includes a push rod engaging end 2620 at one end that engages with the dust cup cover latch 2220, a push rod contact end 2640 at the other end that contacts one end of the trigger rod 5600, a push rod button 2660 that unlocks the dust cup cover latch 2220, and a push rod groove 2680 adjacent to the push rod button 2660 and close to the push rod contact end 2640. The dust cup also includes a dust cup slide rail 2060 that moves in conjunction with the push rod 2600, a dust cup protrusion 2064 housed in the push rod groove 2680, and a slide rail housing 2500 that shields the dust cup slide rail 2060 and the push rod 2600 from external influences. The direction of movement of the push rod 2600 is parallel to the center direction of the dust cup cavity 2020.

[0027] The motor 3000 is preferably a DC brushed or brushless motor, wherein the center direction of the motor 3000 is the same as the center direction of the dust cup cavity 2020.

[0028] The power supply 4000 is located at one end of the air inlet housing 1200 and is adjacent to the handle housing 1600; one end of the power supply 4000 is flat to ensure that the entire vacuum cleaner can be placed on a horizontal surface without tipping over. The motor 3000 and the power supply 4000 at least partially overlap on the same projection plane. The projection plane is located on this horizontal plane.

[0029] The unlocking device 5000 includes a pull rod 5200, a rotating member 5400 with one end connected to one end of the pull rod 5200, a trigger rod 5600 with one end connected to the other end of the rotating member 5400 and the other end causing the push rod 2600 to move, and a support 5800 for fixing the rotating member 5400. The movement of the push rod 2600 causes the dust cup cover 2200 to rotate and open. The pull rod 5200 includes a pull rod ring 5220 suitable for a user's finger to pull, a pull rod connecting end 5240 located at one end of the pull rod 5200 and having a connecting end hole 5242 for causing the rotating member 5400 to rotate, a pull rod receiving end 5260 located at the other end of the pull rod 5200 and above the pull rod ring 5220, and a pull rod spring 5280 sleeved on the pull rod receiving end 5260, wherein the pull rod ring 5220 is closer to the pull rod receiving end 5260 than the pull rod connecting end 5240. The rotating member 5400 includes a first rotating shaft end 5420 located at one end and within the connecting end hole 5242, a second rotating shaft end 5440 located at the other end, and a central rotating shaft end 5460 located between the first rotating shaft end 5420 and the second rotating shaft end 5440. The trigger rod 5600 includes an arc-shaped groove 5620 at one end for receiving the second rotating shaft end 5440, and a trigger end 5640 at the other end for abutting against the push rod contact end 2640. The support 5800 includes a pair of fixed support arms 5820 disposed opposite each other, and a support cavity 5840 located between the fixed support arms 5820 for receiving the rotating member 5400. Each fixed support arm 5820 is provided with a fixed support arm hole 5824 for receiving the central rotating shaft end 5460.

[0030] When working, combine Figure 4 As shown, the airflow containing coarse dust enters the dust cup chamber 2020 from the inside of the air inlet duct housing 1200 and undergoes cyclone separation. Large dust and garbage are separated, while fine dust and airflow enter the mesh cover 2400 for secondary cyclone filtration. After secondary cyclone filtration, it is filtered again by the filter element 2460, and then enters the motor 3000 and is finally discharged to the outside. Once the dust in the dust cup cavity 2020 exceeds a certain amount, the user's finger pulls the pull ring 5220 of the lever backward, compressing the spring 5280 of the lever. At the same time, the connecting end hole 5242 of the rotating component 5400 moves backward, causing the first rotating shaft end 5420 to rotate backward. Since the central rotating shaft end 5460 is supported by the support 5800, the second rotating shaft end 5440 moves forward, pushing the arc-shaped groove 5620 of the trigger rod 5600 forward, which in turn pushes the push rod mating end 2620 of the push rod 2600 to release the engagement with the dust cup cover lock 2220. As a result, the dust cup cover 2200 is rotated open to expose one end of the dust cup cavity 2020, allowing the dust in the dust cup cavity 2020 to be poured into the trash can, thus facilitating one-handed operation by the user.

[0031] The advantages of this utility model are: it can be unlocked and ash emptied from a long distance, keeping away from pollution and making it easy for users to operate, especially enabling one-handed operation.

[0032] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
