The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The dust cup of the existing handheld dust collector with one-key dust pouring function is arranged at the front part of a dust collector shell, and meanwhile, the dust cup cover is pivoted at the front part or the bottom part of the dust collector shell so as to cover a dust outlet of the dust cup. However, the dust pouring switch of the dust cup cover of the existing handheld dust collector is correspondingly positioned at the front part of the shell. At this time, the dust dumping switch is far away from the dust collecting switch at the rear part of the dust collector shell, so that the dust dumping is inconvenient to dump by one hand, and a handle at the rear part is also needed to be held by one hand, or the handle is called as a handheld part, and the other hand moves forwards to operate the dust dumping switch. The handheld dust collector is convenient to use when a narrow space is cleaned, the handheld dust collector is obviously inconvenient to use in the narrow space through two-hand operation, meanwhile, the dust pouring action is not simple and convenient enough, and the dust pouring function through one-key falling needs to be further achieved.

The handheld dust collector provided by the embodiment of the application moves the dust pouring button to the handheld part of the shell, so that when one hand of a user holds the handheld part, the dust pouring button can be directly operated, and the dust cup cover opens the dust outlet under the associated action of the dust pouring button. At the moment, the user can conveniently pour out dust and the like accumulated in the dust cup by aligning the dust outlet of the dust collector shell with the garbage bag, so that the one-key dust pouring function is realized in the true sense, and the convenience of the handheld dust collector is further improved.

The inventive concepts of the present application will be further described with reference to certain preferred embodiments.

A handheld dust collector can be a charging type dust collector or a direct current type dust collector, and is not limited in the specification.

The dust collector mainly comprises a shell, and one end of the shell is provided with a handheld part. An air inlet and an air outlet are formed on the shell. The air outlet is located at the end of the handheld portion, and the air inlet is located on the end face of one end, corresponding to the handheld portion, of the shell. Therefore, one end of the shell with the air inlet can be used as the front end of the shell, namely the working side, and the corresponding handheld part is used as the rear end of the shell, namely the user side. Namely, the air inlet direction is taken as the front, and the air outlet direction is taken as the back.

The air duct in the housing may be compact, with the air flow path from the air inlet being tortuous. At this time, the hand-held portion may be configured as a vertically arranged grip. Or the air duct of the shell can be straight-through, namely the air entering from the air inlet flows out after passing through the dust cup, the motor and the air outlet which are sequentially arranged on the same straight line. Accordingly, the hand-held portion may be configured as a handle or grip arranged in parallel or in line along the same line as previously described.

Referring to fig. 1 and 2, the following description will take the case where the air duct is straight.

A switch member is disposed on the hand-held portion 11 on the rear side of the housing 10, the switch member being provided on the hand-held portion 11 and configured to be movable between a first position and a second position. The arrangement of the switch member on the hand-held portion 11 may facilitate the user to operate the switch member with a thumb or other finger while holding the hand-held portion 11 with a single hand.

Specifically, the hand-held portion 11 is generally provided with a dust suction switch 1 in a humanized manner. The dust suction switch 1 is generally disposed at a position where the thumb of the hand can be operated. That is, the hand-held portion 11 referred to herein includes not only a portion that can be held by the palm of a hand, but also an area that is accessible to the thumb when in a holding posture. The switch piece can be arranged close to the dust collection switch 1, so that the switch piece or the dust collection switch 1 can be selectively operated to pour dust and collect dust when the handheld part 11 is held by a single hand.

The switch element can be designed as a push button, electric switch or touch switch.

Referring to fig. 1, 2 and 3, a mounting groove is formed in the front side of the upper top wall of the handheld portion 11 of the housing 10 along the axial direction of the handheld portion 11, and a push button 2 is mounted in the mounting groove. A switch shell is arranged on the mounting groove, and a moving space of the push button 2 is limited between the switch shell and the groove wall of the mounting groove. The switch housing 10 is provided with a waist-shaped hole, and the waist-shaped hole is communicated with the movable space.

The push button 2 includes an arc plate 201 installed inside the installation groove. The top wall of the arc plate 201 protrudes upward from a substantially middle position thereof and extends to form a boss 202, or a round flat key is directly fixed to the arc plate 201 by welding or screws to form the boss 202. The arc plate 201 is installed in the activity space and can move back and forth. And the boss 202 is located in the kidney-shaped hole at this time, and the size of the kidney-shaped hole defines the range of the forward and backward movement of the boss 202, i.e., the push button 2.

In order to facilitate the pushing of the push button 2 by the thumb of the user, at least one transverse rib is formed on the top of the boss 202 in a protruding manner. To increase the friction between the thumb and the push button 2 or to receive the force of the push directly exerted thereon by the thumb.

The inside of the shell 10 is a motor cavity, and a motor 12 is arranged in the motor cavity. When the motor 12 is operated, a negative pressure is generated in the motor cavity, so that external dusty air flow and the like can enter the dust cup 13 through the air inlet A. Under the filtering action of the dust cup, dust and the like in the airflow are separated and collected in the dust cup 13, and clean airflow passes through the air duct in the handheld part 11 through the motor cavity and flows out from the air outlet at the rear end of the handheld part 11.

The cross-sectional area of the air outlet is smaller than that of the air inlet, so that more dust can be absorbed, and meanwhile, the airflow can flow out more quickly.

A substantially horizontal hole is formed in the front end surface of the housing 10. The dirt cup is fixedly mounted in the hole in the axial direction of the housing 10. At this time, the dirt cup 13 is generally configured as a cylindrical pipe member having one end opened. The opening is the dust outlet B of the dust cup. I.e. the dust outlet B is arranged facing away from the handgrip 11.

Preferably, the dirt cup 13 is completely enclosed within the aperture.

The specific structure of the dirt cup 13 is not essential to the protection of the present application, but is also known to those skilled in the art, and will not be described herein.

A hinge seat is formed at the outer edge portion of the front end surface of the housing 10, and a dust cup cover 14 is hinged to the hinge seat. The hinge base may be configured to either side of the housing 10, for example, at the side of the housing 10, preferably at the bottom of the housing 10, and disposed opposite to the hand-held portion 11 at the top of the rear end of the housing 10. At this moment, after the user holds the operating switch piece of the handheld part 11 with one hand to open the dust cup cover, dust is poured by one key, and after the dust cup cover is closed by one hand after the dust cup cover touches other objects by the handheld part, the dust cup cover can be closed by one hand.

Referring to fig. 2, when the dust cup lid 14 is opened, the dust cup lid 14 swings downward under the action of gravity, so that the dust outlet of the dust cup can be exposed. The flip angle of the dirt cup can be defined by the hinged mount.

When the dust cup lid 14 is in a closed position, it is naturally tilted downward by gravity or rests on a hinged seat after being detached from the housing 10. When the dust cup cover 14 is connected with the front end surface of the shell 10 to cover the dust outlet B, the dust cup cover 14 is in the open position.

An air inlet pipe 141 is formed on the dust cup cover 14 by extending forwards and bundling. The air inlet duct 141 is substantially in line with the hand grip 11. The end of the air inlet pipe 141 is the air inlet a. The air inlet duct 141 allows the air inlet to be more concentrated. At this time, the dust cup cover 14 not only covers the dust outlet B but also functions as a dust suction passage. Therefore, a dust suction pipeline penetrating through the dust cup cover 14 is also constructed on the dust cup cover 14. The dust collection pipeline is also provided with a filtering component which is used for primarily filtering dust-containing airflow and preventing particles and impurities which damage the motor 13 from entering the dust collector.

And can be connected with other brush head components, connecting pipes, long connecting pipes or bent pipes and other auxiliary parts through the air inlet pipe 141.

The connection of the dirt cup lid 14 to the housing 10 may be by snap fit, magnetic attraction, or other techniques known in the art.

Referring to fig. 4 and 5, in order to facilitate one-key dust pouring, the connection between the dust cup lid 14 and the housing 10 can be rapidly released after the switch element is operated, a long arc-shaped hole is formed in the rear end surface of the dust cup lid 14, and an insert 5 is installed in the long arc-shaped hole. The longitudinal section of the insert 5 is configured in the form of a transverse U. I.e. the lower arm of the insert 5 may be welded directly or secured to the dirt cup cover 14 by a bead, or press block. The connecting portions of the two arms of the insert 5 are arranged toward the front side, and then the upper arm of the insert 5 extends toward the rear side of the housing 10.

A clamping hole is arranged on the front end surface of the shell 10 to be matched and clamped with the insert 5, so that the dust cup cover 14 is kept at the closed position.

In some embodiments, the fixing of the insert 5 may alternatively be an electromagnet arranged in the radial direction of the housing 10, which is held in the closed position by the upper arm of the projecting insert 5 being pressed against the housing 10 in the radial direction. Other techniques known in the art may also be used.

Referring to fig. 4 and 5, the end of the insert 5 has a small protrusion extending radially of the housing 10. Meanwhile, a recessed groove is formed at the top of the housing 10 and extends forward to communicate with the front end surface of the housing 10, and a rectangular or oblong hole is formed at the front end surface of the housing 10. The bottom wall of the hole is moved upward by a certain distance so that the bottom wall and the bottom wall of the rectangular hole or the oblong hole form a step in the axial direction of the housing 10. Or the top wall of the rectangular hole or the oblong hole and the slot top wall form a step. The hole is the aforementioned card hole. The snap hole allows the upper arm of the insert 5 to penetrate into it. After the upper arm of the insert 5 is inserted into the fastening hole, the small projection 501 abuts against the step surface C of the fastening hole, so that the insert 5 is locked and the dust cup cover 14 is kept in a closed state.

The stepped surface C may be inclined toward the rear of the housing 10 or arranged in the radial direction of the housing 10.

Referring to fig. 6, preferably, in some embodiments, the lower arm of the insert 5 may be hollowed out on the medial-anterior side to increase the flexibility of the insert 5. So that the insert 5 can be inserted or removed more smoothly.

Preferably, the insert 5 is arranged in correspondence with the hinge seat, i.e. the hinge seat is arranged at the bottom side of the housing 10, while the insert 5 is arranged at the top of the housing 10. The moment arm of insert 5 and the hinge mount is made longer and the force provided by insert 5 to close cup lid 14 is greater.

The release of the connection of the insert 5 to the housing 10 results from the forward pushing of the push button 2, while a slider is also provided inside the housing 10 in order to transmit the pushing force of the push button 2 to the insert 5. In the aforementioned groove, a slider is arranged, i.e., in the passage, the slider moves back and forth in the axial direction of the housing 10. The rear end of the slider is connected to the aforementioned push button 2, and the front end of the slider is connected to the insert 5. Of course, the slider can move in other directions, and only when the switch member moves from the first position to the second position, the slider moves towards the dust cup cover 14, namely the insert 5 is pushed out of the clamping hole.

Since the housing 10 is not integrally formed, the housing 10 generally includes a rear main portion and a front detachable portion for easy installation. The main body part is the motor cavity and the handheld part 11, and the detachable part is a part used for installing the dust cup and connected with the dust cup cover 14.

Thus, the slider also comprises two parts, namely a first pushing member 4 and a second pushing member 3, wherein the first pushing member 4 is fixedly connected with the second pushing member 3, the first pushing member 4 is connected with the inserting member 5, and the second pushing member 3 is connected with the switch member.

In particular, with reference to fig. 5, the side of the upper arm of the insert 5 facing the handle 11 is configured with a bevel against which the end of the first pusher 4 abuts. When the slider follows the push button 2 to move forward, the insert 5 and the first push member 4 are relatively displaced in the radial direction of the housing 10 due to the presence of the ramp. Thereby disengaging the small bump 501 of the insert 5 from the aforementioned step surface C. Dust cup cover 14 flips under its own weight and carries insert 5 out of the card hole and then into the open position.

The slope may be disposed toward the front side of the housing 10 or may be disposed toward the rear side of the housing 10. Specifically, when the step surface C is located on the groove bottom wall, the inclined surface is disposed toward the rear side of the housing 10. When the step surface C is located on the groove top wall, the slope is disposed toward the front side of the housing 10.

The end face of the first push element 4, which is connected to the inclined surface, can be correspondingly designed as an inclined surface, i.e. as a second inclined surface. The inclined plane is attached to the second inclined plane. The cooperation of the two inclined surfaces can prevent the first pushing member 4 from being stuck on the inclined surfaces during interaction. Or the end face of the first push member 4 connected to the inclined surface may be correspondingly configured as an arc-shaped surface.

Specifically, the first pushing member 4 may be a rod, a plate or a pipe, which is not limited herein. Preferably an arcuate plate 201.

The second pushing piece 3 is connected with the pushing button 2 and connected with the first pushing piece 4, so that when the pushing button 2 moves forwards, the pushing button 2 pushes the second pushing piece 3 to move forwards, the second pushing piece 3 pushes the first pushing piece 4 to move forwards, the first pushing piece 4 pushes the inserting piece 5 to move forwards to be disconnected with the step surface, and the dust cup cover 14 is released from the closed position.

The second pusher 3 is primarily intended to engage the first pusher 4 and the push button 2. The connection of the first pushing member 4 and the second pushing member 3 can be fixed by welding, bonding, etc., or a force for making the first pushing member 4 and the second pushing member 3 fit with each other can be allowed to exist by the limitation of size, for example, the inserting member 5 is inserted into the slot to force the first pushing member 4 to move backwards by a first distance, the second pushing member 3 is installed in the housing 10, the maximum distance of the backward movement is limited by the push button 2 at the rear side thereof, when the first pushing member 4 and the second pushing member 3 are installed in place, the first pushing member 4 moves backwards by the first distance to make the second pushing member 3 move backwards by about equal to the maximum distance, that is, the first pushing member 4 and the second pushing member 3 naturally abut against each other, that is, the connection is fixed.

Between the second pusher member 3 and the housing 10 there is a resilient member configured to normally urge the second pusher member 3 in a direction away from the dirt cup. Namely, the elastic piece pushes the second elastic piece towards the rear of the shell 10, so that the insert 5 is kept attached to the step surface, and the dust cup cover 14 is in a closed state.

Specifically, referring to fig. 3, two sides of the second pushing member 3 extend left and right to form two ears, and springs 6 are respectively arranged between the two ears and the housing 10 along the axial direction of the housing 10. The spring 6 is in a compressed energy storage state when the push button 2 moves forwards, so that the spring 6 pushes the second pushing piece 3 backwards, and then pushes the push button 2 backwards. When the push button 2 is released, the spring 6 pushes the second pusher 3 backwards, the push button 2 causing the second pusher 3 and the push button 2 to reset.

In some embodiments, the second pushing member 3 may also be arranged as a rod or a tube, in which case the elastic member may be arranged as a spring that is sleeved on the second pushing member 3.
