It will be appreciated by those skilled in the art that the present disclosure divides the motorized broom into a cleaning head assembly 1, a dirt tray assembly 2, and a handle bar 3, for ease of description only. This does not mean that the cleaning head assembly 1, the dust box assembly 2 and the operation lever 3 are independent parts, and those skilled in the art can adjust the relationship among the cleaning head assembly 1, the dust box assembly 2 and the operation lever 3 according to the needs (for example, for convenience of communication and description), for example, the dust box assembly 2 includes the operation lever 3, that is, the operation lever 3 is attached to the dust box assembly 2 and is a part of the dust box assembly 2.

As shown in fig. 2 to 5, the cleaning head assembly 1 includes a housing 11, a roll brush 12, a support wheel 13, a foot pedal 14, a motor (not shown), a battery (not shown), and a belt (not shown). Wherein the rolling brush 12 is rotatably mounted on the front portion of the housing 11 and is connected with the motor through a transmission belt, and the battery is in driving connection with the motor, so that the battery can provide electric energy for the motor, and the motor can drive the rolling brush 12 to rotate. The battery and motor are fixedly mounted to the rear of the housing 11. The support wheels 13 are rotatably mounted to the housing 11 for supporting the cleaning head assembly 1 to travel. A foot pedal 14 is fixedly mounted to the rear side of the housing 11 for unlocking the dirt tray assembly 2 locked to the housing 11. For convenience of operation, the cleaning head assembly or the operating rod can be provided with a rechargeable battery, and the battery can be fixedly arranged on the cleaning head assembly or the operating rod or can be detachably connected with the cleaning head assembly or the operating rod.

With continued reference to fig. 2 to 5, the front portion of the housing 11 is provided with a roller brush mounting cavity 111 for mounting the roller brush 12, the middle portion of the housing 11 is provided with a dust box mounting cavity 112 for mounting the dust box assembly 2, and the rear portion of the housing 11 is provided with a motor mounting cavity (not shown) for mounting a motor and a battery mounting cavity (not shown) for mounting a battery. The belt is located outside the side wall of the dust box mounting chamber 112 (i.e., the belt is hidden inside by the housing 11), and the belt is drivingly connected to the motor and the roll brush 12, respectively. Since the technical means of drivingly connecting the motor and the roller brush 12 together by means of a drive belt are conventional in the art, they will not be described in greater detail here.

With reference to fig. 2 to 5, a hook 113 is disposed on a sidewall of the dust box mounting cavity 112 as a fastening structure, and the housing 11 locks the dust box assembly 2 into the dust box mounting cavity 112 through the hook 113. The rear portion of the housing 11 is also formed with a recess 114 for dividing a motor mounting cavity and a battery mounting cavity for mounting a battery, the recess 114 being capable of accommodating at least a part of the operating lever 3. In other words, the operation lever 3 can be fitted into the groove 114.

Further, as shown in fig. 2 and 5, the roll brush installation cavity 111 and the dust box installation cavity 112 communicate with each other. The housing 11 is further provided with a wedge structure 115 as a target object, and the wedge structure 115 is located between the roller brush installation cavity 111 and the dust box installation cavity 112. In addition, two wedge structures 115 are distributed in the up-down direction in fig. 4, and the two wedge structures 115 are respectively located at the upper end and the lower end of the rolling brush installation cavity 111.

Further, as shown in fig. 2, 4 and 5, a slope surface 116 is formed between the rolling brush installation cavity 111 and the dust box installation cavity 112, and the slope surface 116 is matched with the rolling brush 12. During the rotation of the roller brush 12, the roller brush 12 can transfer the garbage on the ground to the slope surface 116, and then the garbage is transferred to the dust box assembly 2 in the dust box installation cavity 112 under the action of the slope surface 116.

As shown in fig. 6 to 8, the dust box assembly 2 includes a box body 21, a lower cover 23, an upper cover plate 24, a baffle 25, and a card slot 26. An inlet (not shown) is formed on the front plate 212 of the box body 21, and an outlet (not shown) is formed at the bottom of the box body 21. One end of the lower cover 23 is pivotally connected to the bottom of the case body 21, and the other end (free end) of the lower cover 23 can be snapped together by a snap fit structure provided on the case body 21 and a snap fit structure provided on the lower cover 23, thereby closing the outlet.

With continued reference to fig. 6-8, upper cover 24 is positioned on top of box 21, and a portion of upper cover 24 extends and overhangs one side of the inlet (barrier 25). As can be readily seen from fig. 6 to 8, the portion of the upper cover plate 24 has a semicircular structure, and furthermore, it is possible for those skilled in the art to arrange the portion in an arc-shaped structure as needed.

As shown in fig. 6 and 7, two transparent members 241 (e.g., glass or transparent plastic) are disposed on the upper cover 24, the two transparent members 241 are distributed along the length direction of the box body 21, and the two transparent members 241 are used for allowing a user to observe the inside of the box body 21, so that the user can pour in time when there is a lot of garbage in the box body 21.

As shown in fig. 6 and 8, the shutter 25 is pivotally connected to the box body 21 and can close the entrance on the front side plate 212. Specifically, shutter 25 can rotate to an open state and a closed state, and the bottom of shutter 25 in the closed state is located outside box body 21 and abuts against the outer surface of box body 21; the bottom of the shutter 25 in the open state is located outside the case body 21 and separated from the outer surface of the case body 21.

Although not shown in the drawings, in a preferred embodiment of the present disclosure, a gap is formed between the bottom of the shutter 25 in the closed state and the case 21, which allows the wedge structure 115 on the cleaning head assembly 1 to be inserted, and thus rotates the shutter 25 from the closed state to the open state.

Preferably, the front side plate 212 is provided with a strip-shaped protrusion (not shown in the drawing) at a lower side of the inlet, and a length of the strip-shaped protrusion in a left-right direction of the box body 21 is smaller than that of the baffle 25, so that a bottom of the baffle 25 in a closed state abuts against the strip-shaped protrusion and the aforementioned gap is formed with the box body 21.

Further, although not shown, the dirt tray assembly 2 further includes a torsion spring disposed between the shutter 25 and the tray body 21 for automatically rotating the shutter 25 from the open state to the closed state and maintaining the closed state to close the inlet, so as to prevent the escape of the garbage in the tray body 21 from the inlet on the front side plate 212.

The automatic opening process of the shutter 25 will be briefly described with reference to fig. 9 and 10.

As shown in fig. 9 and 10, during installation of the dust box assembly 2 into the dust box installation cavity 112, the wedge structure 115 on the housing 11 is inserted into the gap between the baffle 25 and the box body 21. Then, as the dust box assembly 2 continues to be installed, the wedge structure 115 will gradually dig into the gap and thereby overcome the spring force of the torsion spring and rotate the flap 25 to the open position.

As shown in fig. 9 and 10, in the state where the dust box assembly 2 is mounted in the dust box mounting chamber 112, the lowest edge of the inlet on the front side plate 212 is lower than the top end of the slope 116, so that the rotating roller brush 12 can transfer the garbage into the box body 21 through the slope 116. In order to prevent dust in the garbage from falling between the front side plate 212 and the side wall of the dust box installation cavity 112, one skilled in the art may extend the top end of the slope 116 into the box body 21 through the inlet on the front side plate 212 as required.

With continued reference to fig. 9 and 10, in a state in which the dust box assembly 2 is mounted in the dust box mounting cavity 112, the top surface of the dust box assembly 2 (i.e., the top surface of the upper cover plate 24) can constitute a portion of the top surface of the housing 11. The reason is that the dust box mounting cavity 112 is open at the top thereof, and the dust box assembly 2 is mounted in the dust box mounting cavity 112 on the housing 11 from top to bottom.

Referring back to fig. 8, the box 21 is provided with a locking slot 26 matching with the hook 113 of the housing 11. In the state where the dust box assembly 2 is mounted in the dust box mounting cavity 112, the hooks 113 are inserted into the slots 26 (as shown in fig. 11), locking the dust box assembly 2 to the cleaning head assembly 1.

The process of unlocking the dirt tray assembly 2 by the foot pedal 14 is illustrated with reference to fig. 11 and 12.

Fig. 11 is a schematic view showing the positions of the hook 113 and the pedal 14 in the locked state; fig. 12 shows a schematic position diagram of the hook 113 and the foot pedal 14 in the unlocked state.

As shown in fig. 11 and 12, the foot board 14 and the two hooks 113 are pivotally connected to the housing 11, respectively, and the two hooks 113 are drivingly connected to the foot board 14 through a wire harness (not shown) passing around a pulley (not shown) on the housing 11. Preferably, the cleaning head assembly 1 is provided with a return spring for pivoting and retaining the two hooks 113 from the position shown in figure 12 to the position shown in figure 11. Since the provision of a spring to perform this function is conventional in the art, it will not be described herein in any greater detail.

With continued reference to fig. 11 and 12, when it is desired to remove the dirt tray assembly 2 from the cleaning head assembly 1, the user depresses the foot pedal 14, causing the foot pedal 14 to rotate counterclockwise. In the process, the pedal 14 pulls the left hook 113 to rotate counterclockwise through the wiring harness, and pulls the right hook 113 to rotate clockwise until the two hooks 113 are disengaged from the slots 26 on the box body 21. At this time, the user can remove the dirt tray assembly 2 from the cleaning head assembly 1.

As shown in fig. 13 and 14, the operation lever 3 includes a lever body 31, an operation key 32, a jack 33, and a spring 34. The operation key 32 is drivingly connected to the push rod 33, and when the operation key 32 is operated, the push rod 33 is driven to open the lower cover 23 of the dust box assembly 2, so that the garbage in the box body 21 can be poured out from the outlet at the bottom of the box body 21.

With continued reference to fig. 13 and 14, the lever 31 includes a first section 311 connected to the case 21 and a second section 312 provided with the operation keys 32. One end of the first section 311 is pivotally connected to the case 21 and can rotate about a first axis (a horizontal chain line in fig. 13). The other end of the first section 311 is pivotally connected to the second section 312 and is able to rotate about a second axis (the oblique chain line in fig. 13). It can be readily seen from figures 13 and 14 that the first axis is at an angle to the second axis.

Further, a first end bevel (shown by a dotted line in fig. 13) is formed at an end of the first section 311 close to the second section 312, and a second end bevel (shown by a dotted line in fig. 13) is formed at an end of the second section 312 close to the first section 311. The first end inclined surface abuts the second end inclined surface to enable the first section 311 and the second section 312 to relatively rotate to a state of being coaxial with each other (a state shown in fig. 13) or having an angle.

Further, although not shown in the drawings, a limit groove is provided on the first section 311, a limit projection is provided on the dust box assembly 2, and the first section 311 and the second section 312 can be rotated about a horizontal chain line in fig. 13 to a position where the limit projection is fitted into the limit groove. One skilled in the art will appreciate that the retaining groove may also be provided on the second section 312. Alternatively, one skilled in the art may also arrange the aforementioned limiting groove on the dust box assembly 2 and arrange the limiting protrusion matching with the limiting groove on the first section 311 and/or the second section 312, as required.

With continued reference to fig. 13 and 14, the top bar 33 includes a first top bar 331 and a second top bar 332, and the first top bar 331 and the second top bar 332 are disposed in an L-shape. A first inclined surface (not marked in the figure) is formed at one end of the first push rod 331, one end of the second push rod 332 is fixedly connected with the operation key 32, and the other end of the second push rod 332 is in sliding contact with the first inclined surface. The second push rod 332 can drive the first push rod 331 away from the rod body 31 through the first slope and thus force the closed lower cover 23 to be opened.

It can be understood by those skilled in the art that the first inclined surface at the left end of the first top bar 331 in fig. 13 and 14 is a tapered surface, that is, the left end of the first top bar 331 in fig. 13 and 14 is a conical surface, so that the second top bar 332 can abut against the first inclined surface (tapered surface) when rotating to any angle position along with the operating rod 31, thereby driving the first top bar 331 to slide.

As can be seen from fig. 13 and 14, the first push rod 331 is disposed in the first section 311 and can be extended and retracted relative to the first section 311. The spring 34 is disposed between the first push rod 331 and the first section 311 for providing a force for the first push rod 331 to retract the first section 311. A portion of the second lift pin 332 is located in the first section 311, and another portion of the second lift pin 332 is located in the second section 312.

As shown in fig. 13 and 14, the dust box assembly 2 further includes a sliding rod 27 slidably connected to the box body 21, the box body 21 is provided with a snap-fit structure 211 for locking the lower cover 23, and the free end of the lower cover 23 is provided with a snap-fit structure (not marked in the figure), the snap-fit structure 211 can be snapped together with the snap-fit structure, and thus the lower cover 23 closes the outlet at the bottom of the box body 21. One end of the slide bar 27 (the lower end of the slide bar 27 in fig. 13) is formed with a second slope (not labeled in the figure), and the slide bar 27 is in sliding contact with the other end of the first push rod 331 (the right end of the first push rod 331 in fig. 11) through the second slope. The first top bar 331 can drive the slide bar 27 to abut against the engaging structure 211 on the box body 21 through the second inclined surface, and thus the engaging structure 211 is separated from the engaging structure on the lower cover 23.

As shown in fig. 13, in a normal state, the snap-fit structure on the lower cover 23 and the snap-fit structure 211 on the box body 21 are snapped together, and the lower cover 23 closes the outlet at the bottom of the box body 21.

When the dust box assembly 2 needs to dump the garbage, the user pushes the operation key 32 from top to bottom in the direction shown in fig. 13, and thus the second push rod 332 slides down from the position shown in fig. 13 to the position shown in fig. 14, so that the second push rod 332 drives the first push rod 331 to slide rightward from the position shown in fig. 13 to the position shown in fig. 14, so that the first push rod 331 drives the slide rod 27 to slide upward from the position shown in fig. 13 to the position shown in fig. 14, so that the slide rod 27 drives the catch structure 211 to rotate clockwise from the position shown in fig. 13 to the position shown in fig. 14, so that the catch-fit structure on the lower cover 23 disengages from the catch structure 211, and so that the lower cover 23 automatically opens under the action of its own gravity.

It will be understood by those skilled in the art that the snap fit structure on the lower cover 23 and the snap structure 211 on the box body 21 shown in fig. 13 and 14 can be any feasible structure, such as one of them being a hook, the other being a slot, or both being hooks.

Based on the foregoing description, those skilled in the art will appreciate that in the preferred embodiment of the present disclosure, by having the lever 3 fixedly connected to the dirt tray assembly 2, the lever 3 and the dirt tray assembly 2 can be removed from the cleaning head assembly 1 as a single unit without the user having to bend over. Further, by arranging the pedal plate 14 on the cleaning head assembly 2, the user can detach the dust box assembly 2 and the operating rod 3 from the cleaning head by stepping on the pedal plate 14, and the operation is more convenient. Further, through set up the manipulating key 32 that can open dust box subassembly 2 lower cover 23 on action bars 3 for the user is all unnecessary to contact dust box subassembly 2 at the in-process of dismantling dust box subassembly 2 and dumping rubbish, has avoided the raise dust to fly to user's on one's body.
