By providing the locking mechanism 23, the closed state of the cup opening can be maintained when the handheld dust collection device 100 is used normally, and dust can be prevented from spilling.

When the existing hand-held dust collection device is used for cleaning impurities such as dust, a user needs to hold the holding part by one hand and open the cup cover by the other hand, so that the dust pouring operation by the two hands is inconvenient. In order to facilitate the ash pouring operation, in this embodiment, the handheld dust collector 100 further includes an opening mechanism 4 for opening the cup 21. The opening mechanism 4 comprises a release piece 41 and a transmission component, wherein the release piece 41 is movably arranged on the shell, the transmission component is arranged between the shell and the air duct 15, one end of the transmission component is connected with the release piece 41, and the other end of the transmission component can be matched with the cup cover 22, so that the cup cover 22 is driven to move relative to the cup body 21 through the movement of the release piece 41, and then the cup mouth of the cup body 21 is opened.

By providing the opening mechanism 4, the opening process of the cup mouth of the cup body 21 can be simplified, and a user only needs to move the release piece 41, so that the operation is more convenient.

As shown in fig. 2, the release 41 is located above the air chute 15 and the cap 22 is located below the air chute 15. When the user needs to clean the dust in the cup 21, the user can hold the hand holding part 12 with one hand and move the release piece 41 by fingers (such as thumb or index finger) of the same hand to open the cup opening of the cup 21, so that the single-hand dust pouring operation is realized. The release piece 41 is located air flue 1 top, and the user's one hand operation of convenience triggers release piece 41, and the user can be located handheld portion 12 top and be used for triggering release piece 41 when pouring ash with the thumb, and other four fingers are located handheld portion 12's bottom, and single hand operation is more convenient. The cup cover 22 is positioned below the air duct 15, and the ash pouring angle does not need to be adjusted after the cup opening is opened, so that the use is convenient, and the use experience of a user is improved.

In this embodiment, the release member 41 may be located on the air channel portion 11 and at an end near the hand-held portion 12. On the one hand, the release piece 41 is arranged on the air channel part 11, so that the user can be prevented from touching the release piece 41 when holding the handheld part 12, the touch feeling of the user can be improved, and the release piece 41 can be prevented from being touched by mistake; on the other hand, the release member 41 is close to the hand-holding portion 12, so that a user can hold the hand-holding portion 12 with one hand, and at the same time, the release member 41 is triggered by fingers (such as thumb or index finger) of the same hand to move and open the cup body 21, thereby realizing one-hand ash pouring operation, being convenient to use and being beneficial to improving the use experience of the user.

In this embodiment, the release member 41 may be a push button, which is slidably connected to the housing. When a user needs to open the cup mouth of the cup body 21, the cup cover 22 can be driven to move through the transmission assembly by pushing the push button, so that the operation is labor-saving.

In other embodiments, the release member 41 may be a button or knob, which is convenient for the user to operate.

In other embodiments, the release 41 may also be provided on the handpiece 12.

As shown in fig. 2 and 3, to further facilitate the cleaning of dust and other impurities in the dust cup 2 by a user, an opening is provided at one end of the cup body 21 away from the hand-held portion 12, i.e. the cup opening is provided near the air duct inlet 131, and the bottom end of the cup cover 22 is rotatably connected with the cup body 21. The user holds the handheld portion 12 when pouring ash, and the air duct inlet 131 naturally faces downwards, and after the cup opening of the cup body 21 is opened through the release piece 41, the cup cover 22 cannot be located right below the cup opening, and impurities such as dust in the cup body 21 can be poured out through the cup opening of the cup body 21 under the action of gravity, so that the user does not need to adjust the cup opening direction of the cup body 21, and the ash pouring operation is further simplified.

Taking the example that the air duct inlet 131 is positioned at the front end of the machine body 1, the cup body 21 is positioned at the bottom of the machine body 1, the cup opening of the cup body 21 is obliquely arranged, and the cup opening extends from the top of the front end of the cup body 21 to the bottom of the cup body 21 in an inclined and backward manner. According to the cup opening, on one hand, the size of the cup opening can be increased, and dust can be conveniently poured; on the other hand, the deflection angle of the air flow in the flowing direction when entering the dust cup from the air duct 15 can be reduced, so that the air flow enters the cup body 21 under the guiding action of the cup cover 22 which is also obliquely arranged, and the stability of the air flow is maintained.

Illustratively, the cup cover 22 and the cup body 21 can be rotatably connected through a rotation shaft, and the rotation shaft can be located at a position approximately 1/2 of the cup body 21 along the length direction, so that a certain dust collecting space is ensured in the dust collecting cup 2 on the basis of increasing the cup mouth, and the dust collecting space is prevented from being too small.

Preferably, the dirt cup 2 is arranged at the bottom of the housing. On one hand, the dust cup 2 can be prevented from shielding the sight, which is beneficial for a user to observe the cleaning condition of the position to be cleaned; on the other hand, when the user pours ash, the dust and other impurities can be prevented from accumulating on the machine body 1, and the machine body 1 is kept clean in appearance.

In order to prevent the air flow in the air duct 15 from entering between the casing and the outer wall of the air duct 15 through the clamping holes on the inner wall of the clamping groove 133, a sealing layer can be arranged on the outer wall of the air duct 15 at a position corresponding to the clamping holes, and the sealing layer is covered outside the clamping holes, so that the air tightness of the handheld dust collection device 100 is improved.

Alternatively, the sealing layer may be made of a sealant, which can not only improve the sealing effect but also improve the fixing effect of the casing and the end cover 13 by self-adhesion.

Because the wires and the transmission assembly are located in the same space, in order to avoid mutual interference between the transmission assembly and the wires, as shown in fig. 5, a cover plate 14 is further disposed between the casing and the air duct 15, the cover plate 14 is at least partially covered outside the transmission assembly, and a routing channel for accommodating the wires is located between the cover plate 14 and the casing.

To further isolate the wires from the drive assembly, as shown in fig. 6 and 7, a wire slot 151 is also provided on the outer wall of the air duct 15 and/or the cover plate 14, the wires being received in the wire slot 151. The position of the wire can be further fixed by providing the wiring groove 151, and the wire is prevented from moving, thereby preventing the wire from interfering with the transmission assembly.

Optionally, as shown in fig. 8, the top of the sidewall of the wiring groove 151 may also be provided with a wire pressing block 1511. The wire pressing block 1511 can reduce the opening size of the wire groove 151. When the wire is fixed, the wire is pressed to enable the wire to be extruded into the wire groove 151 beyond the wire pressing block 1511, and then the wire pressing block 1511 is located above the wire, so that the wire can be pressed into the wire groove 151 to prevent the wire from being separated from the wire groove 151, and the fixing effect of the wire is improved.

Further, the wire pressing block 1511 may be a wedge, a wedge surface of the wedge is directed toward the other side wall of the wire groove 151, and a distance between the wedge surface and the other side wall is gradually increased from the outside to the inside of the wire groove 151 to press the wire into the wire groove 151 through the wedge surface.

Alternatively, a plurality of wire pressing blocks 1511 may be disposed on the side wall of the wire groove 151, and the plurality of wire pressing blocks 1511 may be disposed on the same side wall of the wire groove 151, or may be disposed on two opposite side walls of the wire groove 151 in a staggered manner.

A push rod 421 is provided at the top of the air duct 15 and extends in the direction of the flow of air in the air duct 15, thereby transmitting the movement of the release piece 41 toward the cup cover 22. The push block 422 extends downwards from the top of the air duct 15 along the outer wall of the air duct 15, so that the push block 422 can be prevented from occupying the space in the air duct 15 on one hand, and the gas flow during vacuum adsorption is ensured; on the other hand, the power can be transmitted from the upper part to the lower part of the air duct 15, so that the cup cover 22 is driven to rotate relative to the cup body 21.

In order to enable the push block 422 to slide more stably relative to the air duct 15, the push block 422 can be in an arch bridge shape, so that the push block 422 can be sleeved on the air duct 15, on one hand, the push block 422 can avoid the air duct 15, and the gap between the shell and the air duct 15 is fully utilized as a mounting space, so that the reduction of the internal space of the air duct 15 caused by the fact that the push block 422 directly passes through the air duct 15 is avoided; on the other hand, the arch bridge-shaped push block 422 is matched with the air duct 15, so that the outer wall of the air duct 15 plays a role in guiding the movement of the push block 422, and the movement of the push block 422 is more stable.

Because push rod 421 is rectangular structure, occupation space is less, and the wire is when following the outer wall wiring of wind channel 15, can set up with push rod 421 interval, avoids wire and push rod 421 contact wearing and tearing to lead to the inefficacy. The push block 422 is straddled on the air duct 15, and the wires are connected with the power supply 5 and the conductive contact pins, and must pass through the push block 422 to be in contact with the push block 422. For this reason, in the present embodiment, the wires and the push rod 421 may be disposed at intervals, and the cover plate 14 may be disposed only above the push block 422 to separate the push block 422 from the wires, so as to avoid the interference between the push block 422 and the wires.

When the cover plate 14 is covered on the push block 422, the top surface of the cover plate 14 is flush with the outer wall of the air duct 15, so that the first wiring groove and the second wiring groove are smoothly connected, wires are prevented from being bent or contacted with edges when entering the second wiring groove from the first wiring groove, and abrasion of the wires is prevented.

To reduce the space occupied by the push rod 421 inside the casing and to avoid interference between the push rod 421 and the wires, the diameter of the push rod 421 is small. In order to ensure the stability of the transmission between the push rod 421 and the push block 422, the push block 422 is convexly provided with a connecting block, and the connecting block is connected or abutted with the push rod 421 so as to drive the push block 422 to move through the movement of the push rod 421, thereby being beneficial to improving the stability of the movement of the push block 422.

In order to avoid the push block 422 to rotate along the circumferential direction relative to the air duct 15, the cover plate 14 is provided with a limiting notch, the connecting block can be arranged in the limiting notch in a sliding manner, and the circumferential positioning of the push block 422 is realized through the cooperation of the connecting block and the limiting notch, so that the movement of the push block 422 is more stable.

Further, a push rod guiding groove 152 is further provided on the outer wall of the air duct 15, and the push rod 421 can be slidably disposed in the push rod guiding groove 152, so that the push rod 421 is prevented from being blocked in the moving process by guiding the sliding direction of the push rod 421 through the push rod guiding groove 152.

The push rod guide groove 152 may be formed by bending an outer wall of the air duct 15 toward the inside of the air duct 15 to form the second rib 155 at the inside of the air duct 15 while forming the push rod guide groove 152. The forming mode of the push rod guide groove 152 is simple in processing mode, is beneficial to ensuring the strength of the air duct 15, and can simultaneously form the second convex rib 155 on one hand, and the second convex rib 155 can guide the air flow in the air duct 15, so that the flowing state of the air flow in the air duct 15 is changed, and the effect of stabilizing the flow is achieved; on the other hand, the distance between the cabinet and the outer wall of the air duct 15 can also be reduced, thereby reducing the size of the hand-held vacuum cleaner 100 in the up-down direction.

In order to make the stress of the push block 422 more uniform, the push block 422 includes a connecting portion 4221 and two opposite push portions 4222. The connecting part 4221 is slidably arranged at the top of the air duct 15, and the connecting part 4221 is connected with the push rod 421; the opposite sides of the connecting portion 4221 are symmetrically provided with pushing portions 4222, the pushing portions 4222 are slidably arranged on the side portions of the air duct 15, and the end portion of each pushing portion 4222 can be matched with the locking mechanism 23 so as to unlock the cup cover 22 and the cup body 21. In this embodiment, the push rod 421 is connected with the connecting block in the middle of the connecting portion 4221, and the pushing portions 4222 symmetrically disposed on both sides can cooperate with the locking mechanism 23, so as to improve the uniformity of the stress of the push block 422, and make the sliding of the push block 422 smoother.

Further, the opening assembly further comprises a first reset member capable of automatically resetting the release member 41 upon release of the release member 41 by a user. In this embodiment, the first restoring member may be a spring, and the spring has a simple structure, low cost, and convenient installation.

Specifically, each pushing portion 4222 is provided with a first reset member, and the first reset members corresponding to the two pushing portions 4222 are symmetrically arranged. One end of the first reset element is abutted against or connected with the pushing part 4222, and the other end is abutted against or connected with the outer wall of the casing or the air duct 15.

When a user pushes the release piece 41, the release piece 41 applies pushing force to the push block 422 through the push rod 421, the push block 422 overcomes the elastic force of the first reset piece to slide, and the first reset piece can play a role of buffering the push block 422 on one hand, so that the push block 422 is prevented from being contacted with the locking mechanism 23 to generate larger impact force; on the other hand, the symmetrically arranged first reset members can also avoid the push block 422 from deflecting, thereby preventing the push block 422 from being jammed during the sliding process.

After the user releases the release member 41, the first reset member resets by driving the pushing part 4222, and the reset of the push block 422, the push rod 421 and the release member 41 is sequentially realized, so that the user can directly lock the cup cover 22 and the cup body 21 after pouring ash, the manual driving of the release member 41 is not needed, and the operation of the user is simplified.

In order to avoid bending of the first reset element during the deformation process, reset mounting posts are disposed on the air duct 15 and/or the pushing portion 4222, and the first reset element may be sleeved outside the mounting posts, so as to avoid the push block 422 from being blocked due to bending of the first reset element.

In other embodiments, the first reset member may be sleeved outside the push rod 421, and reset by pushing the push rod 421, so as to drive the push block 422 and the release member 41 to reset.

In order to improve the aesthetic degree of the handheld dust collection device 100, in this embodiment, the locking mechanism 23 is disposed in the cup 21, and the bottom end of the push block 422 can penetrate through the through hole on the casing and extend into the cup 21, so as to cooperate with the locking mechanism 23 to complete unlocking of the cup 21 and the cup cover 22.

As shown in fig. 11, the locking mechanism 23 includes a first engagement portion 231, a second engagement portion 232, a rotation portion 233, a force receiving portion 234, and a first elastic member. The first clamping part 231 is arranged on the cup cover 22, the rotating part 233 is fixedly arranged in the cup body 21, the second clamping part 232 is rotationally connected with the rotating part 233, and the first clamping part 231 can be matched with the second clamping part 232, so that the cup cover 22 is positioned at a position for closing an opening on the cup body 21 and the cup cover 22 are locked; the force receiving part 234 is connected with the second clamping part 232, can rotate relative to the rotating part 233 synchronously with the second clamping part 232, and the force receiving part 234 is used for being matched with the push block 422; the first elastic member is elastically connected to the second clamping portion 232 and the cup body 21, and the first elastic member can drive the second clamping portion 232 to rotate in a direction clamped with the first clamping portion 231. By arranging the first elastic piece, on one hand, the second clamping part 232 and the first clamping part 231 can be prevented from being separated, so that the locking effect of the cup body 21 and the cup cover 22 is improved; on the other hand, the sealing effect between the cup cover 22 and the cup body 21 can be improved, and the leakage of dust in the cup body 21 is avoided. The rotating portion 233 may be a rotating shaft, two ends of the rotating shaft are fixedly connected with the inner wall of the cup body 21, and the second clamping portion 232 and the force receiving portion 234 may be an integral structure and rotationally sleeved outside the rotating shaft.

In other embodiments, the rotating portion 233, the second clamping portion 232 and the force receiving portion 234 may be integrally formed, and two ends of the rotating portion 233 are rotatably connected to the inner wall of the cup 21.

In this embodiment, the first clamping portion 231 and the second clamping portion 232 are both hook structures. When the handheld dust collection device 100 is normally used, a user can press the cup cover 22 down on the cup body 21, so that the first clamping part 231 and the second clamping part 232 are hooked and locked under the action of the first elastic piece, and the handheld dust collection device is simple in structure, convenient to lock and reliable in sealing effect.

When the dust in the dust cup needs to be cleaned, a user drives the push rod 421 and the push block 422 to move sequentially by pushing the release piece 41, and the push block 422 drives the second clamping part 232 to rotate relative to the rotating part 233 by pushing the stress part 234, so that the second clamping part 232 is driven to be separated from the first clamping part 231, and the cup cover 22 and the cup body 21 are in contact locking, so that the dust can be cleaned conveniently.

In other embodiments, the first clamping portion 231 may be an elastic structure, such as a hook with elasticity, and the elastic force of the first clamping portion 231 can keep the first clamping portion 231 and the second clamping portion 232 in a locked state. The push block 422 can be matched with the first clamping part 231 to unlock the cup cover 22 and the cup body 21, correspondingly, the second clamping part 232 can be fixedly arranged in the cup body 21, and the locking mechanism 23 does not need to be provided with the stress part 234 and the rotating part 233, so that the structure is facilitated to be simplified.

In order to enable the cup cover 22 to automatically flick off relative to the cup body 21 in the unlocking state and keep the unlocking state, the dust collecting cup 2 further comprises a second elastic piece, and the second elastic piece can drive the cup cover 22 to rotate relative to the cup body 21 in the direction of opening the cup mouth of the cup body 21, so that after the cup cover 22 and the cup body 21 are unlocked, the cup cover 22 can be automatically flicked off under the action of the second elastic piece, a user does not need to manually rotate the cup cover 22 or hold the cup cover 22 to keep the state of the cup cover 22, and dust cleaning operation is simpler.

Optionally, the second elastic member may be a second torsion spring, where the second torsion spring is sleeved on a rotating shaft connected between the cup cover 22 and the cup body 21, and two ends of the second torsion spring respectively abut against the cup body 21 and the cup cover 22 to drive the cup cover 22 to rotate relative to the cup body 21, and the torsion spring has a simple structure and low cost, so that the cost of the handheld dust collection device 100 is controlled.

In this embodiment, each pushing portion 4222 is correspondingly provided with a second clamping portion 232, each second clamping portion 232 is correspondingly provided with a first clamping portion 231 matched with the second clamping portion 232, and the first clamping portions 231 are located on two opposite sides of the same end of the cup cover 22, so that the cup cover 22 is favorable for being balanced in stress when being locked with the cup body 21, stress concentration of the cup cover 22 due to uneven stress is avoided, and sealing effect between the cup cover 22 and the cup body 21 can be improved.

Optionally, the first elastic element may be a first torsion spring, and the first torsion spring is sleeved outside the rotating shaft. The first elastic member may be an elastic arm 235, where one end of the elastic arm 235 is connected to the rotating portion 233, and the other end of the elastic arm 235 can abut against the inner wall of the cup body 21 when the cup cover 22 closes the cup opening of the cup body 21, so that the elastic arm 235 deforms to store elastic potential energy, and can also provide a locking force for the cooperation of the first clamping portion 231 and the second clamping portion 232.

In this embodiment, the first elastic member is preferably the elastic arm 235, because the volume of the torsional spring is great, compare the scheme that uses the torsional spring, the first elastic member can save installation space for the elastic arm 235, increases the dust collection space in the cup 21, reduces the frequency of user's clearance dirt cup, is favorable to improving user's use experience.

Alternatively, the second clamping portion 232, the force receiving portion 234 and the elastic arm 235 may be integrally formed, so that the number of components of the locking mechanism 23 can be reduced, and the processing and assembly are facilitated.

Because the casing is provided with various control keys, the various control keys comprise, but are not limited to, a power switch and a speed regulating button, in order to avoid that a user rotates the cup cover 22 to open the cup mouth by touching the release piece 41 by mistake when using the handheld dust collection device, and a gap H is arranged between the output end of the transmission component and the locking mechanism when the cup body 21 is closed by the cup cover 22.

As shown in fig. 12, when the release member 41 is not subjected to an external force, the push block 422 is positioned at the initial position by the first restoring member, and a gap H is provided between the push block 422 and the force receiving portion 234.

When the user touches the release piece 41 by mistake and drives the push block 422 to move, and when the movement distance of the push block 422 is smaller than the gap H, the push block 422 is not contacted with the stress part 234, so that the cup mouth on the cup body 21 is ensured to be in a closed state, and the problem that the cup mouth is opened or the sealing between the cup cover 22 and the cup body 21 is poor due to the fact that the user touches the release piece 41 by mistake is avoided.

The specific size of the gap H may be set according to the actual structural size.

Optionally, for convenience of use, the power switch, the speed adjusting button and the release member 41 may also be specifically positioned according to the frequency of use, so that the control key with high frequency of use is relatively close to the hand-hold portion 12, so as to be convenient for the user to operate, and correspondingly, the control key with low frequency of use is relatively far away from the hand-hold portion 12, so as to avoid the user from touching by mistake during the operation.

Illustratively, the power switch, governor button and release 41 may be arranged from top to bottom on the housing to avoid false bumps by the user.

In order to further facilitate the user to open the cup opening by pushing the release member 41, the length N of the force receiving portion 234 along the radial direction of the rotating portion 233 is smaller than the length M of the second clamping portion 232 along the radial direction of the rotating portion 233, so that when the rotating portion 233 rotates by a certain angle, the rotation track of the end portion of the force receiving portion 234 is shorter, and the rotation track of the end portion of the second clamping portion 232 is longer, and therefore when the release member 41 moves by a shorter distance, the first clamping portion 231 and the second clamping portion 232 can be separated, and the cup opening is opened.

When the user opens the cup mouth, the distance that the release member 41 needs to be pushed to move is short, and the user can operate the cup with one hand conveniently.

Example two

The present embodiment provides a dust collecting apparatus which is further improved on the basis of the first embodiment to improve the sealing effect of the cup cover 22 and the cup body 21.

Because the locking mechanism 23 is when locking bowl cover 22 and cup 21, exert locking force to bowl cover 22, will lead to bowl cover 22 and locking mechanism 23 complex position stress concentration, and then lead to whole bowl cover 22 atress inhomogeneous, will influence the sealed effect of bowl cover 22 and rim of a cup's cooperation position to lead to dust collection cup 2 gas leakage, influence result of use and use experience.

When the cup cover 22 closes the cup opening, a part of the cup cover 22 (hereinafter referred to as a sealing part) is used for sealing in cooperation with the dust collection cavity 211, and the rest of the cup cover 22 (hereinafter referred to as a locking part) corresponds to the mounting cavity 212 and is used for cooperation with the locking mechanism 23.

Through the arrangement, the locking part on the cup cover 22 matched with the locking mechanism 23 is positioned at the outer side of the dust collection cavity 211, and the locking force applied by the locking mechanism 23 to the cup cover 22 is concentrated on the locking part, so that the influence of the locking force applied to the cup cover 22 on the sealing part can be reduced, and the sealing effect of the cup cover 22 on the dust collection cavity 211 is improved.

In order to further improve the sealing effect of the dust collecting cavity 211 and the sealing part, as shown in fig. 14 and 15, the sealing member 25 may be integrally injection molded on the cup cover 22, so that the processing technology is simple, the structure fixing sealing member 25 is not required to be additionally arranged, and the installation position of the sealing member 25 and the cup cover 22 can be prevented from being changed, thereby improving the sealing effect of the dust collecting cavity 211. Illustratively, the seal 25 is a seal ring.

In this embodiment, the bottom end of the cup cover 22 is rotatably connected with the cup body 21, so that the locking mechanism 23 matched with the cup cover 22 is arranged close to the machine body 1, and the transmission assembly is matched with the locking mechanism 23 to unlock the cup cover 22 and the cup body 21. One end of the cup cover 22 far away from the dust collection cavity 211 (namely the top end of the cup cover 22) is matched with the locking mechanism 23, so that the distance between the locking force applied by the locking mechanism 23 and the dust collection cavity 211 can be increased, the influence of the locking force on the sealing part is further reduced, uneven stress on the sealing part 25 contacted with the sealing part is avoided, and the sealing effect of the cup cover 22 on the dust collection cavity 211 is improved.

When the cup cover 22 is locked with the cup body 21 through the locking mechanism 23, the force applied by the locking mechanism 23 to the cup cover 22 has a trend of driving the cup cover 22 to rotate continuously in the direction of closing the cup opening, in addition, the cup cover 22 can be subjected to the elastic force applied by the second elastic piece to the cup cover 22, the elastic force has a trend of driving the cup cover 22 to rotate in the direction of opening the cup opening, and the elastic force can be counteracted with the force applied by the locking mechanism 23 to the cup cover 22, so that the moment born by the cup cover 22 is balanced, the even stress of the sealing piece 25 is facilitated, and the sealing effect of the dust collecting cavity 211 is improved.
