Example 1

As shown in fig. 1 and 2, a dustpan includes: the cleaning device comprises a dustpan 110, comb teeth 121, a cleaning piece 130 and a driving mechanism 150, wherein the comb teeth 121 are arranged on the dustpan 110; the cleaning member 130 is slidably connected with the comb teeth 121 in the extending direction of the comb teeth 121, the driving mechanism 150 comprises a power member 157, a power input wheel 152 and a power output wheel 154 which are in transmission connection, the power member 157 is connected with the power input wheel 152, the power output wheel 154 is connected with the comb teeth 121 or the cleaning member 130, the power member 157 is suitable for providing power for the power input wheel 152, and the cleaning member 130 and the comb teeth 121 are driven to slide relatively in the extending direction of the comb teeth 121 through the power output wheel 154, so that the cleaning member 130 cleans the comb teeth 121, and the angular speed of the power input wheel 152 is smaller than that of the power output wheel 154.

Continuing to combine with fig. 1, the dustpan 110 has a top wall, a bottom wall and a side wall, wherein the top wall, the bottom wall and the side wall enclose a containing cavity, and the front edge of the bottom wall of the dustpan 110 protrudes out of the front edge of the top wall, so that objects such as garbage can be conveniently cleaned into the containing cavity of the dustpan 110. The front edge of the top wall has a notch, and comb teeth 121 may be disposed, and in general, the comb teeth 121 may be sequentially disposed in a plurality along the width direction of the dustpan 110. As shown in fig. 2 and 4, the cleaning member 130 is provided with a cleaning hole 1301, and the comb teeth 121 pass through the cleaning hole 1301, so that the cleaning hole 1301 is sleeved on the comb teeth 121, and the cleaning member 130 and the comb teeth 121 relatively move along the extending direction of the comb teeth 121, so that the object to be cleaned on the comb teeth 121 falls into the dustpan 110; in the above embodiment of the cleaning member 130, the cleaning member 130 may be configured to have a comb 121 without the cleaning hole 1301, and be inserted into the gaps of the plurality of comb 121, so that the cleaning of the comb 121 can be achieved by sliding the cleaning member with respect to the plurality of comb 121.

With continued reference to fig. 2, the power element 157 provides power to the power input wheel 152, so that the power input wheel 152 rotates, the power input wheel 152 transmits power to the power output wheel 154, and the power output wheel 154 acts on the comb teeth 121 or the cleaning element 130, so that the comb teeth 121 and the cleaning element 130 can slide relatively in the extending direction of the comb teeth 121. The angular velocity of the power input wheel 152 is smaller than the angular velocity of the power output wheel 154, so that the rotation angle of the power input wheel 152 can be reduced under the condition that the rotation angle of the power output wheel 154 is fixed, and the power element 157 does not need to move too much distance, i.e. too much movement space is not required to be reserved for the power element 157 on the dustpan 110.

Specifically, the power input wheel 152 and the power output wheel 154 are gears, and the gears are directly meshed or indirectly meshed to form a gear transmission of the power output by the power element 157, so that the gear transmission has high efficiency, compact structure and reliable operation, and is beneficial to saving the installation space of the driving mechanism 150.

Further, as shown in fig. 2 and 5, the power input wheel 152 and the power output wheel 154 are drivingly connected by a drive gear set having an angular velocity greater than the angular velocity of the power input wheel 152 and less than the angular velocity of the power output wheel 154.

The connection between the power input wheel 152 and the power output wheel 154 via the transmission gear set is advantageous for further reducing the rotation angle of the power input wheel 152, thereby further reducing the movement space reserved for the power member 157.

Still further, the drive gear set includes a coaxially disposed large gear 158 and a small gear 156, the small gear 156 being meshed with the power input wheel 152, the large gear 158 being meshed with the power output wheel 154. Wherein the diameter of the large gear 158 is larger than the diameter of the small gear 156.

The angular speed of the power output wheel 154 is three times of the angular speed of the transmission gear set, and the angular speed of the transmission gear set is three times of the angular speed of the power input wheel 152, so that the power input wheel 152 inputs a smaller angular speed, and the power output wheel 154 can obtain a larger angular speed, thereby saving time, labor and space. For example, when the power input wheel 152 rotates 20 °, the driving gear set may rotate 60 °, and the power output wheel 154 may rotate 180 °, and when the power output wheel 154 rotates 180 °, so that the first transmission portion 153 drives the second transmission portion 155 to move from the first position to the second position, and then the cleaning member 130 moves relatively to the comb teeth 121 by a distance between the first position and the second position. The rotation of the power output wheel 154 can drive the second transmission part 155 to move from the first position to the second position through the first transmission part 153, the first position and the second position are symmetrical about a central vertical plane, the central vertical plane is a vertical plane of the extending direction of the comb teeth 121 where the rotation center 159 of the power output wheel 154 is located, and the distance between the first position and the second position is a first distance. The distance between the first position and the second position is the distance that the cleaning member 130 moves relative to the comb teeth 121, and is also the first distance.

Further, as shown in fig. 2 and 7, the power output wheel 154 is provided with a first transmission portion 153, the comb teeth 121 or the cleaning member 130 is provided with a second transmission portion 155, the first transmission portion 153 is in transmission connection with the second transmission portion 155, the power output wheel 154 rotates to drive the first transmission portion 153 to rotate around a rotation center 159 of the power output wheel 154, and then drive the second transmission portion 155 to move in an extending direction of the comb teeth 121, and further drive the cleaning member 130 and the comb teeth 121 to slide relatively in the extending direction of the comb teeth 121.

In the extending direction of the comb teeth 121, the cleaning member 130 is slidably connected with the comb teeth 121, so that the cleaning member 130 and the comb teeth 121 can generate relative displacement, and objects, such as filiform objects, on the comb teeth 121 can be scraped out and then fall into the dustpan 110. Wherein, the driving mechanism 150 can be used for driving the comb teeth 121 or the cleaning member 130, so that relative displacement can be generated between the two in the extending direction of the comb teeth 121. As shown in fig. 3 and 5, the power output wheel 154 has a rotation center 159, the motion track of the first transmission portion 153 is arc-shaped or circular, when the power output wheel 154 rotates around the rotation center 159, the power output wheel 154 drives the first transmission portion 153 and the second transmission portion 155 to cooperate with each other, so that the arc-shaped motion track of the first transmission portion 153 is converted into the linear motion track of the second transmission portion 155, and the cleaning member 130 or the comb teeth 121 can be driven to generate displacement, so that the cleaning member 130 and the comb teeth 121 slide relatively in the extending direction of the comb teeth 121, and the cleaning member 130 cleans the comb teeth 121.

According to the dustpan provided by the embodiment of the utility model, the first transmission part 153 is arranged on the power output wheel 154, and the second transmission part 155 matched with the first transmission part 153 is arranged on the cleaning member 130 or the comb teeth 121, when the power output wheel 154 rotates, the power output wheel 154 can convert the rotation of the power output wheel into the movement of the second transmission part 155 in the extending direction of the comb teeth 121, and as the first distance of the movement is greater than or equal to the distance between the first transmission part 153 and the rotation center 159 of the power output wheel 154, the movement stroke of the second transmission part 155 is increased, namely the relative sliding distance between the comb teeth 121 and the cleaning member 130 is increased, so that the cleaning member 130 or the comb teeth 121 can run for a long enough distance to push filaments such as hair on the comb teeth 121 into the dustpan 110.

Specifically, the first transmission portion 153 is a sliding column, the sliding column is disposed offset from a rotation center 159 of the power output wheel 154, the second transmission portion 155 is a sliding slot, and the sliding column is slidably engaged in the sliding slot.

The power take-off wheel 154 may be coaxially provided with a turntable 151, and the spool has a rod shape, and one end of the spool is fixed at a position of the turntable 151 deviated from the rotation center 159, which may be understood as a distance L between the spool and the rotation center 159. The sliding column is inserted into the sliding groove and can slide in a matched manner with the sliding groove. Taking the example that the second transmission part 155 is provided on the cleaning member 130, the sliding groove may be provided as a long hole, and the length of the long hole may be enough to ensure that the cleaning member 130 slides along the extension direction of the comb teeth 121 without upward or downward movement. When the cleaning member 130 is normally placed or used, the bottom surface of the dustpan 110 is horizontal or approximately horizontal, and the extending direction of the elongated hole is vertical. It may also be understood that the extending direction of the elongated hole is perpendicular to the extending direction of the comb teeth 121, so that the first distance generated by the first transmission portion 153 in the extending direction of the comb teeth 121 can make the running distance of the cleaning member 130 longer. Of course, the extending direction of the elongated hole may also be set at other angles with the extending direction of the comb teeth 121.

More specifically, the spool is provided at the edge of the disk surface of the power take-off wheel 154 facing the chute such that the distance L between the spool and the center of rotation 159 of the power take-off wheel 154 may approximate the radius R of the power take-off wheel 154. When the sliding column rotates 180 ° along with the rotation of the power output wheel 154, the moving distance of the sliding column is close to the diameter of the power output wheel 154, or the sliding groove is arranged on the cleaning member 130, for example, the moving distance of the cleaning member 130 may also be close to the diameter of the power output wheel 154, and if the diameter of the power output wheel 154 is larger, the moving distance of the cleaning member 130 is also larger.

In further embodiments, the first transmission portion 153 is a tooth and the second transmission portion 155 is a rack, the tooth being engaged with the rack. In the example where the second transmission part 155 is provided on the cleaning member 130, the rack is provided on the cleaning member 130, the teeth are provided on the power output wheel 154, and when the power output wheel 154 rotates, the teeth drive the rack, thereby moving the cleaning member 130.

Further, the power member 157 is a rotating pedal, the rotating shaft of the rotating pedal is coaxially connected with the rotating shaft of the power input wheel 152, the rotating pedal is connected with an elastic restoring member 160, the rotating pedal is stepped on to drive the elastic restoring member 160 to elastically deform, the stepping force of the rotating pedal is removed, and the elastic restoring force of the elastic restoring member 160 can drive the rotating pedal to restore.

Continuing to combine with fig. 1, the side wall of the dustpan 110 is provided with an opening 1101, one end of the rotating pedal is provided with a rotating shaft, the power input wheel 152 is coaxially arranged and connected with the rotating shaft, and the other end of the pedal extends out of the opening 1101. The elastic restoring member 160 may be a spring, and the elastic restoring member 160 may be disposed above the rotating pedal, where the lower end of the elastic restoring member 160 is fixedly connected with the rotating pedal. The spring can be driven to elastically deform by stepping on the rotating pedal, after the stepping force of the rotating pedal is removed, the rotating pedal rotates upwards under the action of the restoring force of the spring, and then the power output wheel 154, the first transmission part 153 and the second transmission part 155 are driven to move reversely, so that the cleaning piece 130 and the comb teeth 121 are driven to slide reversely relatively, and objects such as hairs hung on the comb teeth 121 can be scraped again and the cleaning piece 130 is reset again.

It should be further noted that the movement of the cleaning member 130 may be driven by a knob, and the knob may be used instead of the rotating pedal. Or the cleaning member 130 can be driven by a button, a rack is arranged on the inner side of the button and meshed with the power input wheel 152, and when the button is pressed, the button can drive the rack to move, and the rack can drive the power input wheel 152 to rotate.

More specifically, when the rotating pedal is depressed, the rotating pedal rotates downward by a half stroke of 20 degrees, so that the power input wheel 152 rotates synchronously by 20 degrees, the power input wheel 152 is meshed with the pinion 156, then the power input wheel 152 drives the pinion 156 and the large gear 158 to rotate synchronously clockwise by 60 degrees, the large gear 158 drives the power output wheel 154 to rotate synchronously counterclockwise by 180 degrees, so that the sliding column can move up and down to the opposite side from the position shown in fig. 3, when the sliding column moves up and down to the right from the position shown in fig. 3, the sliding column slides up in the sliding groove and drives the sliding groove to move to the right to the central position of the power output wheel 154, when the sliding column moves down and drives the sliding groove to move to the right side edge of the power output wheel 154, at this time, the cleaning piece 130 moves up to the same distance as the sliding groove, and cleaning of the comb teeth 121 is realized.

When the rotating pedal continues to rotate downwards for the other half of the stroke, which is equal to 20 degrees, the rotating pedal does not rotate downwards any more when the rotating pedal abuts against the lower limiting piece 170. In this process, rotating the pedal will drive the power input wheel 152 to rotate 20 degrees again counterclockwise, then drive the pinion 156 and the bull gear 158 to rotate 60 degrees again clockwise, then drive the power output wheel 154 to rotate 180 degrees again counterclockwise, so that the slide column moves from the opposite side of the position shown in fig. 3 to the initial position shown in fig. 3, when the slide column moves from the opposite side of the position shown in fig. 3 to the left and down, the slide column slides downward in the slide groove, and drives the slide groove to move leftward to the center position of the turntable 151 of the power output wheel 154, when the slide column moves leftward and upward in the slide groove, and drives the slide groove to continue to move leftward to the left edge of the turntable 151, namely the initial position shown in fig. 3, at this time, the cleaning member 130 moves leftward by the same distance as the slide groove, thereby realizing the reset of the cleaning member 130.

Further, it will be appreciated that the rotation of the power take-off wheel 154 causes the cleaning member 130 to slide relative to the comb teeth 121 to clean the object hanging on the comb teeth 121, and if the steering of the power take-off wheel 154 is a forward rotation in this state, the power take-off wheel 154 may also be a reverse rotation. The reverse rotation of the power output wheel 154 can drive the first transmission portion 153 to reversely rotate around the rotation center 159 of the power output wheel 154, and further drive the second transmission portion 155 to reversely move a first distance in the extending direction of the comb teeth 121, and further drive the cleaning member 130 and the comb teeth 121 to reversely relatively slide in the extending direction of the comb teeth 121, so that the cleaning member 130 and the comb teeth 121 are reset. Specifically, when the rotating pedal rotates by an angle, the cleaning hole 1301 on the cleaning member 130 slides to the end of the comb teeth 121, and when the rotating pedal is released, the rotating pedal can reversely rotate under the reset action of the elastic reset member 160, so that the power input wheel 152 can be driven to reversely rotate, and then the pinion 156 and the large gear 158 reversely rotate, and the power output wheel 154 reversely rotates, so that the reverse rotation of the power output wheel 154 can be realized, and the reset of the relative movement of the cleaning member 130 and the comb teeth 121 is realized. The timing of the forward rotation, reverse rotation and reverse rotation of the power take-off wheel 154 is freely operated by the user, and the reverse rotation is not necessarily driven by the elastic restoring member 160, and may be driven by the user independently.

In another embodiment, the power member 157 is a rotating pedal, the rotating shaft of the rotating pedal is coaxially connected with the rotating shaft of the power input wheel 152, and the dustpan 110 is provided with a limiting member 170 for limiting the rotating angle of the rotating pedal.

With continued reference to fig. 3, the second half of the stroke is 20 degrees when the rotating pedal continues to rotate downward, and the rotating pedal does not rotate downward when the rotating pedal abuts against the lower limiting member 170.

With continued reference to fig. 3 and 6, the dustpan further includes a mounting box 140, the mounting box 140 is disposed in the dustpan 110, the cleaning member 130 is slidably supported on the mounting box 140, wherein the driving mechanism 150 is mounted in the mounting box 140, and the power output wheel 154 is rotatably connected with the mounting box 140.
