Detailed Description

Fig. 1 shows a hand-held vacuum cleaner 100 according to an embodiment of the present invention, which can clean various surfaces including floor surfaces by vacuum, and the cleaner 100 can also be attached with various cleaning tools and the like.

For the description in relation to the drawings, the terms "upper", "lower", "right", "left", "rear", "front", "vertical", "horizontal", "inner", "outer" and derivatives thereof should be related to the present invention as oriented in fig. 1, which defines the handle portion 12 at the rear of the entire hand-held vacuum cleaner 100, and the air inlet duct 11 at the front of the entire hand-held vacuum cleaner 100, from the perspective of a user holding the hand-held vacuum cleaner 100 during normal cleaning. However, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary.

As shown in fig. 1, the hand-held vacuum cleaner 100 includes a main body 1, a rechargeable battery pack 2 mounted under the rear of the main body 1, a suction motor 3 (see fig. 2) mounted above and behind the main body 1, and a dust separating and collecting device located at the front side of the suction motor 3. The dust collecting and separating device of the present example comprises a cyclone separating assembly 4, and the cyclone separating assembly 4 can separate and store solid garbage in dust-containing airflow in a dust collecting chamber by utilizing a centrifugal separation mode. The hand-held vacuum cleaner 100 of the present example can also be stably supported on a table by the rechargeable battery pack 2.

The main body 1 has an inclined handle portion 12, a support ramp portion 13 located on the front side of the handle portion 12, a dust-laden air stream inlet 14, a clean air outlet, and an air stream path extending between the dust-laden air stream inlet 14 and the clean air outlet. The main body 1 has a substantially horizontally arranged air inlet duct 11, and the dust-laden air stream inlet 14 is located at the forefront end of the air inlet duct 11. The cyclone separation assembly 4 is fixedly supported above the air inlet duct 11. The support ribs 13 are located between the cyclone assembly 4 and the rechargeable battery pack 2. The handle portion 12 is located on the rear side of the support ramp 13, which handle portion 12 can be grasped by a user with a hand to effect handling of the cleaner 100. The supporting inclined rib part 13 plays a role in stabilizing the dust collector, and can also play a role in assisting the handle when a user is required to lift the dust collector to clean the surface at a high place, specifically: the user grips the supporting diagonal rib part 13 and the handle part 12 to lift or grip the cleaner 100, respectively, so that the operation is more flexible and labor-saving.

In the illustrated embodiment, the suction motor 3 is mounted within a motor housing 15 (see figure 2) of the main body 1 and is in fluid communication with the cyclonic separating assembly 4. The suction motor 3 is located downstream of the cyclonic separating assembly 4 and the clean air outlet is located downstream of the suction motor 3. The external dust-containing air flow can be continuously sucked into the cyclone separation assembly 4 from the dust-containing air flow inlet 14 at the front end part of the air inlet pipe 11 by the suction force of the suction motor 3 for gas-solid separation.

As shown in fig. 2 and3, the cyclone separation assembly 4 comprises a cylindrical outer wall 41, the outer wall 41 lying laterally above the air inlet duct 11. The outer wall 41 includes a circumferential side wall portion and a bottom wall portion 413, the outer wall 41 having a center line X passing through the bottom wall portion 413. In this example, the circumferential side wall is divided into two sections, a front section is a front circumferential side wall 411 and a rear section is a rear circumferential side wall 412, and the bottom wall 413 is located on the front side of the front circumferential side wall 411; wherein the inner side of the rear circumferential side wall 412 defines the cyclone chamber 42, and the front circumferential side wall 411 and the bottom wall portion 413 together define the dust collection chamber 43 for collecting the garbage separated from the cyclone chamber 42. The dust collecting chamber 43 in this example is located at the front side of the cyclone separating chamber 42, and the two chambers are penetrated in front and back directions, and the rotation axis of the cyclone separating chamber 42 is along the direction of the center line X. The cyclone chamber 42 and the dust collection chamber 43 are effectively partitioned in the front-rear direction by the dust skirt 55. The cyclonic separating chamber 42 has air inlets 421 located in the rear circumferential side wall 412. The dust-containing gas flow entering the cyclone chamber 42 from the gas inlet 421 is collected in the dust collection chamber 43 after gas-solid separation. The structure of the air inlet duct 11, the air inlet 421 is arranged to facilitate a spiral rotary flow from the air inlet 421 into the cyclonic separating chamber 42.

The bottom wall portion 413 is located at the foremost end of the outer wall 41, the bottom wall portion 413 being hinged to the front end portion of the front circumferential side wall 411 of the outer wall 41 such that the bottom wall portion 413 is movable between a closed position and an open position. The dust collection chamber 43 is covered when the bottom wall portion 413 is in the closed position and can discharge the garbage accumulated in the dust collection chamber 43 outward when the bottom wall portion 413 is in the open position.

The filter screen 5 is arranged within the cyclone chamber 42. The filter 5 is cylindrical and extends in the same direction as the center line X of the cyclone chamber 42. The filter screen 5 includes a first end portion 51, a second end portion 52, and a mesh portion 53 interposed between the first end portion 51 and the second end portion 52. The second end portion 52 is closer to the bottom wall portion 413 than the first end portion 51. For the embodiment shown in the drawings, the second end 52 is forward, the first end 51 is rearward, and the mesh portion 53 is therebetween. The mesh portion 53 is provided with a plurality of meshes. These mesh openings provide air outlets from the cyclonic separating chamber 42. The filter 5 has an air discharge passage 54 connected to an air outlet, and air flowing out of the air outlet can continue downstream of the cyclone chamber 42 through the air discharge passage 54. In this example, the dust-blocking skirt 55 is tapered, and the dust-blocking skirt 55 is fixedly connected to the second end 52 of the filter screen 5 and extends along the periphery of the second end 52. The mesh part 53 of the filter screen 5 may be a metal filter screen or an injection-molded member having a mesh shape. The mesh on the mesh portion 53 may be a round hole, a square hole, or a narrow strip hole.

The ash removing part 6 is used for cleaning the garbage in the dust collecting chamber 43. The ash removing member 6 of the present example includes an ash pushing portion 61 provided in the dust collection chamber 43 and movable along the center line X, that is, the ash pushing portion 61 is movable forward and backward along the center line X. During the movement, the ash pushing portion 61 is realized with a storage position (position shown in fig. 3) close to the second end 52 of the filter screen 5 and inside the dust skirt 55 and an operating position (position shown in fig. 13) close to the bottom wall portion 413 and away from the dust skirt 55. When the dust pushing portion 61 moves from the storage position to the operating position, that is, in a direction approaching the bottom wall portion 413, the dust pushing portion 61 performs pushing of the dust falling into the dust collection chamber 43 toward the bottom wall portion 413 or pushing out of the dust collection chamber 43.

In this example, the soot pushing portion 61 includes a disk-shaped substrate 611 in the middle and a flexible deformation portion 612 arranged at the periphery of the substrate 611. The flexible deformations 612 of this example comprise bundles of fluff distributed along an umbrella-shaped face. In other embodiments, the flexible deformation may be an annular wiper. The base plate 611 is integrally provided with a boss 613 extending outwardly on a side surface 6111 facing away from the bottom wall portion 413, the boss 613 protruding into the exhaust channel 54. The flexible deformation portion 612 includes an inner end portion 6121 and an outer end portion 6122 opposite the inner end portion 6121. Wherein the inner end 6121 is connected to the base 611. When the ash pushing portion 61 is in the storage position, the flexible deformation portion 612 can be folded inside the dust skirt 55 and has a folded radial profile. The flexible deformation portion 612 is located on the front side of the dust skirt 55 when the dust pushing portion 61 is in the operating position, in which state the outer end 6122 of the flexible deformation portion 612 contacts the inner wall surface 4110 of the front circumferential side wall 411 when the dust pushing portion 61 is in the operating position; the ash pushing portion 61 has a diverging radial profile. In other embodiments, the radial profile may also be arranged as a parallel profile.

When the ash pushing portion 61 in this example is pushed in the direction of the bottom wall portion 413 along the center line X, the base plate 611 can push the trash in the middle of the dust collection chamber 43 toward the bottom wall portion 413, and the flexible deformation portion 612 can push the trash near the inner wall surface 4110 of the front circumferential side wall 411 and the trash adhering to the inner wall surface 4110 of the front circumferential side wall 411 toward the bottom wall portion 413; on the one hand, the dust collector can compress the garbage in the dust collection chamber 43 into clusters, so that the loose garbage is effectively prevented from being scattered around the air by one direction after being discharged from the dust collection chamber 43; on the other hand, the base plate 611 can function to assist the dust to flow out of the dust collection chamber 43, and the flexible deformation portion 612 can function to wipe the dust. The ash pushing portion 61 can enable the user to simultaneously clean the inner wall surface 4110 of the dust collection chamber 43 and clean the outer wall during the process of discharging the garbage in the dust collection chamber 43, and the user does not need to clean the inner wall secondarily.

The surface cleaning body 7 is installed in the cyclone chamber 42 for cleaning the wall surface in the cyclone chamber 42 of dust. The surface cleaning body 7 is annular and arranged at the periphery of the filter screen 5. As shown in fig. 4, the surface cleaning body 7 includes an annular base 71, inner cleaning heads 72 and outer cleaning heads 73 at both inner and outer ends of the annular base 71. The surface cleaning body 7 is movable within the cyclonic separating chamber 42 along the centre line X between a first position (the position shown in figures 2 and 3) and a second position (the position shown in figure 13); during movement from the first position to the second position, the inner cleaning head 72 and the outer cleaning head 73 simultaneously contact the outer surface 50 of the filter screen 5 and the inner wall surface 4120 of the rear circumferential side wall 412 of the outer wall 41, respectively. The inner cleaning head 72 and the outer cleaning head 73 may be flexible wiper strips, sponge or brush structures.

In this example, the inner cleaning head 72 and the outer cleaning head 73 of the surface cleaning body 7 contact the outer surface 50 of the filter screen 5 and the inner wall surface 4120 of the rear circumferential side wall 412 of the outer wall 41, respectively, during movement of the surface cleaning body 7, which can wipe off dust adhering to the outer surface 50 of the filter screen 5 and the inner wall surface 4120 of the rear circumferential side wall 412 of the outer wall 41, the action of wiping off dust can not only avoid the problem of reduced dust separation efficiency due to clogging of the filter screen 5, but also can keep the effective volume of the cyclone chamber always the same by wiping off dust adhering to the inner wall surface of the outer wall and the outer surface of the filter screen.

As shown in fig. 5, the bottom wall portion 413 includes a disk-shaped bottom wall body 4131, an ear portion 4132 located at one side portion of the bottom wall body 4131, and a hook portion 4133 located at the other side portion of the bottom wall body 4131. Ear 4132 has a first connection end 41321 and a second connection end 41322. The hook 4133 is provided with a third connecting end 41331, in this example, the hook 4133 is designed to have a certain deformation amount.

As shown in fig. 6, the first connecting end 41321 of the ear 4132 is hinged to the front circumferential side wall 411 of the outer wall 41 by a first pivot 4134. The second connecting end 41322 of the ear 4132 is hinged to an end portion of the lever 84 described below by a second pivot 4135. The front circumferential side wall 411 of the outer wall 41 is provided with a projection 4114 at a corresponding position.

As shown in fig. 7, the third connecting end 41331 of the hook portion 4133 is locked to the outer wall 41 by a projection 4114 on the front circumferential side wall of the outer wall 41 when the bottom wall portion 413 is in the closed position. While the hook 4133 will be released from the front circumferential side wall of the outer wall 41 when the bottom wall portion 413 is in the open position.

The motor 8 is mounted in a motor mounting chamber 16 spaced from the rear side of the cyclonic separating chamber 42. The motor 8 is simultaneously connected with the bottom wall part 413, the ash pushing part 61 and the surface cleaning body 7 in a transmission way so as to realize the action of driving the three parts. By operating the motor 8, dust cleaning of the cyclone chamber 42 and the dust collection chamber 43 can be achieved. A control key (not shown) capable of triggering the operation of the motor 8 is provided on the outer contour surface of the main body 1, and is preferably installed near the handle portion 12 so that a user can operate the control key with the thumb or index finger of the palm holding the handle portion 12.

As shown in fig. 8, transmission mechanisms including a gear 81, a first rack 82, a second rack 83, a link 84 provided with a sliding groove 841 at the rear, a cover 44, and a cover 45 are provided between the motor 8 and the bottom wall portion 413, the ash pushing portion 61, and the surface cleaning body 7. A rod 85 is integrally provided at the rear of the second rack 83, and a pair of rods 86 extending in a direction parallel to the center line X are provided at both ends of the rod 85. In this example, the second rack 83, the lever 85, and the lever 86 are integrally formed as a single piece. The lever 86 has a pair of lugs 861, and a movable member 87 is provided on the front side of the lugs 861. The front side of the moving member 87 is provided with a push rod 88.

As shown in fig. 9 to 10, the gear 81 is fixed to the output shaft of the motor 8, the first rack gear 82 and the second rack gear 83 are engaged with the left and right side teeth portions of the gear 81, respectively, the front portion of the first rack gear 82 is slidably mounted in the sliding groove 841 at the rear portion of the link 84 by the pin 822, and the front portion of the link 84 is hinged with the second connection end 4322 by the second pivot 435. The first rack 82 and the link 84 are located outside the outer wall 41 and are shielded by a cover 44 disposed outside the outer wall 41. The front part of the second rack 83 is positioned in the exhaust passage 54 inside the filter screen 5 and is fixed to the ash pushing part 61 by a boss 613. The tip end of the lever 86 is fixed to the annular base 71 of the surface cleaning body 7. The front end of the rod 88 is adjacent to a projection 4114 on the outer wall 41. The push rod 88 is located outside the outer wall 41 and has a cover 45 disposed outside the outer wall 41. The cover 44 and the cover 45 are respectively on opposite sides of the circumferential side wall portion of the outer wall 41.

In this example, the sliding groove 841 can enable the first rack 82 to perform a blank stroke relative to the connecting rod 84, and the blank stroke can enable the bottom wall portion 413, the ash pushing portion 61 and the surface cleaning body 7 to move in advance during the moving process of the bottom wall portion 413, the ash pushing portion 61 and the surface cleaning body 7, after a certain stroke, for example, the ash pushing portion 61 and the surface cleaning body 7 move to half of the total stroke, the push rod 88 moves again, and finally the push rod 84 moves again, so that when the ash pushing portion 61 and the surface cleaning body 7 move to the maximum stroke, the bottom wall portion 413 just completes the switching from the closed position to the open position. And the moving sequence of the bottom wall portion 413, the ash pushing portion 61 and the surface cleaning body 7 is exactly opposite thereto during the resetting of these components.

In other embodiments, a transmission different from the above-described transmission mechanism structure may be employed as long as the movement of the bottom wall portion 413, the ash pushing portion 61, and the surface cleaning body 7 can be triggered.

As further shown in fig. 1, the main body 1 is provided with a motor upstream filter 9 upstream of the suction motor 3 and downstream of the cyclone chamber 42. The motor upstream filter 9 can re-filter the air flowing out of the openings of the filter screen 5, and the re-filtered intake air is sucked into the suction motor 3.

As shown in fig. 11, in order to facilitate the removal and installation of the motor upstream filter 9, the top of the main body 1 is provided with a slot 17 between a rear circumferential side wall 412 of the outer wall 41 and the motor housing 115, and the mouth of the slot 17 extends to the outer contour surface of the top of the main body 1. In this example, the slot 17 is vertically opposite to the motor mounting chamber 16, i.e., the slot 17 is located outside the motor mounting chamber 16. The motor upstream filter 9 is configured to be removably fitted into the slot 17. The insertion direction of the upstream filter 9 of the motor in this example is perpendicular to the center line X, i.e., from top to bottom.

As shown in fig. 8, 11, 12, the motor upstream filter 9 includes a filter element 91 (e.g., a hepa filter, a filter sponge, etc.) and a support 92 for mounting the filter element 91 in the slot 17. The support 92 defines a cartridge mounting cavity therein in which the cartridge 91 is received when the filter 9 upstream of the motor is mounted in the slot 17. The support 92 further comprises an outer cover 922, the outer cover 922 closing off the mouth of the slot 17 and being fixed to the top part of the main body 1 when the motor upstream filter 9 is mounted in the slot 17, the outer cover 922 also forming part of the outer contour of the vacuum cleaner. In order to facilitate the user in assembling the motor upstream filter 9, a locking mechanism 93 is provided between the support 92 and the main body 1, which can be unlocked. When cleaning of the filter cartridge 91 in the motor upstream filter 9 is required, this is achieved by unlocking the locking mechanism 93 and pulling the motor upstream filter 9 out of the slot 17. In this example, in order to make the structure compact, one of the parts of the transmission mechanism, the moving member 87, is mounted on the support 92 and located inside the outer cover 922, and the moving member 87 can move up and down with respect to the support 92.

In other embodiments, the upstream filter of the motor may be an integral component, i.e., the filter element is integrally formed with the support body, so long as the upstream filter of the motor is configured to be removable from and attachable to the slot.

As shown in fig. 13, when the user rotates the motor 8 around the first direction by operating the control key, the first rack gear 82 moves backward with the rotation of the gear 81, and the front portion of the first rack gear 82 slides in the slide groove 841 while the link 84 does not move. At the same time, the second rack 83 moves forward along with the rotation of the gear 81, the second rack 83 simultaneously drives the ash pushing part 61 and the surface cleaning body 7 to move forward, the ash pushing part 61 compresses and solidifies the garbage in the dust collecting chamber 43 toward the bottom wall part 413 and simultaneously cleans the inner wall surface 4110 of the front circumferential side wall 411 of the outer wall 41, and the inner cleaning head 72 and the outer cleaning head 73 of the surface cleaning body 7 clean the outer surface 511 of the filter screen 5 and the inner wall surface 4120 of the rear circumferential side wall 412 of the outer wall 41 by contacting the outer surface 50 of the filter screen 5 and the inner wall surface 4120 of the rear circumferential side wall 412 of the outer wall 41, respectively; at this time, during the movement of the second rack 83, the moving member 87 will be driven to move forward, and then the movement of the moving member 87 will push the push rod 88 to move forward, so that the push rod 88 further pushes the third end 41331 of the hook 4133 forward to disengage from the protrusion 4114, and the bottom wall 413 is unlocked; when the second rack 82 cannot slide in the sliding groove 841, the second rack 82 pulls the link 84 to move backward, thereby triggering the ear 4132 of the bottom wall portion 413 to rotate around the first pivot 4134 and the second pivot 4135 at the same time, the bottom wall portion 413 is switched from the closed position to the open position, and the garbage in the dust chamber 43 is pushed out by the ash pushing portion 61.

In contrast, when the user rotates the motor 8 around the second direction opposite to the first direction by operating the control key, the first rack gear 82 will move forward with the rotation of the gear 81 and push the link 84 forward, the forward movement of the link 84 will trigger the bottom wall portion 413 to rotate around the first pivot 4134 and the second pivot 4135 simultaneously in the opposite direction to the former direction, and as the bottom wall portion 413 rotates, the third connecting end 41331 of the hook 433 will rotate to the boss 4114 and be locked by the boss 4114, and the third end 4331 will be pushed backward by the third connecting end 41331 and further push the mover 87 to reset, the bottom wall portion 413 enters the closed position; at the same time, the second rack 83 will bring the ash pushing portion 61 and the surface cleaning body 7 back.

In this case, the surface cleaning body and the ash pushing portion may be operated in advance, and the bottom wall portion may be driven to rotate after both ends. In other embodiments, the motor drive mechanism may also be arranged to accommodate simultaneous actuation of the surface cleaning body, the ash pushing portion and the bottom wall portion. In addition, in other embodiments, the surface cleaning body may also be arranged with only an inner cleaning head. The ash pushing portion may be configured in other ways to facilitate pushing the refuse toward the bottom wall portion.
