Example 1

As shown in fig. 3 and 5, a dustpan includes: the dustpan comprises a dustpan body 110, comb teeth 121, a cleaning piece 130 and a power piece 157, wherein the comb teeth 121 are arranged on the dustpan body 110; the cleaning member 130 is slidably connected with the comb teeth 121 in the extending direction of the comb teeth, the power member 157 is connected with the comb teeth 121 or the cleaning member 130, and the power member 157 outputs at least one set of first power and second power when moving in the first direction M; the first power can drive the cleaning piece 130 and the comb teeth 121 to slide relatively in the forward direction in the extending direction of the comb teeth, so that the cleaning piece 130 cleans the comb teeth 121; the second power can drive the cleaning member 130 and the comb teeth 121 to relatively slide in the opposite direction in the extending direction of the comb teeth, so that the cleaning member 130 and the comb teeth 121 are reset.

Continuing to combine with fig. 1 and 6, 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 from the front edge of the top wall, so that objects such as garbage can be cleaned into the containing cavity of the dustpan 110 conveniently. 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. 1 and 4, the cleaning member 130 is provided with a cleaning hole 1301, the comb teeth 121 pass through the cleaning hole 1301, and the cleaning member 130 and the comb teeth 121 move relatively along the extending direction of the comb teeth 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 have a similar structure to the comb teeth 121 without the cleaning hole 1301, and may be inserted into the gaps of the plurality of comb teeth 121, so that the cleaning of the comb teeth 121 can be achieved by sliding the cleaning member with respect to the plurality of comb teeth 121.

The forward direction and the reverse direction are opposite to each other.

As shown in FIG. 5, the dustpan provided by the utility model drives the cleaning member 130 and the comb teeth 121 to perform forward relative sliding by outputting the first power when the power member 157 moves in the first direction M so as to clean the comb teeth 121, and also drives the cleaning member 130 and the comb teeth 121 to perform reverse relative sliding by outputting the second power when the power member 157 moves in the first direction M so as to reset the cleaning member 130 and the comb teeth 121, and the movement direction of the power member 157 is along the first direction M in the cleaning and resetting processes, so that the power member 157 does not need to be reversed when the cleaning and resetting processes are switched, and the operation of the power member 157 is more convenient.

Further, as shown in fig. 2, the dustpan further includes a rotating member, a first transmission portion 153 disposed on the rotating member, and a second transmission portion 155 disposed on the comb teeth 121 or the cleaning member 130, where the power member 157 is connected to the rotating member, and the first transmission portion 153 is in transmission connection with the second transmission portion 155, and when the power member 157 moves in the first direction M, at least one set of first power and second power are output to the rotating member, the first power can drive the rotating member and the first transmission portion 153 to rotate along the second direction N, the first transmission portion 153 rotates along the second direction N and can drive the second transmission portion 155 to move forward along the extending direction of the comb teeth, so as to drive the cleaning member 130 and the comb teeth 121 to slide relatively in the extending direction of the comb teeth, and the second power can also drive the rotating member and the first transmission portion 153 to rotate along the second direction N, and the first transmission portion 153 can drive the second transmission portion 155 to move reversely along the extending direction of the comb teeth, so as to drive the second transmission portion 155 and the comb teeth 121 to slide relatively in the extending direction of the comb teeth.

As shown in fig. 2 and fig. 4, the rotating member has a rotation center 159, the motion track of the first transmission portion 153 is arc-shaped or circular, and when the rotating member rotates around the rotation center 159, the rotating member drives the first transmission portion 153 to cooperate with the second transmission portion 155, 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 relatively slide in the extending direction of the comb teeth, and the cleaning member 130 cleans the comb teeth 121. The power member 157 outputs the first power and the second power to the rotating member, and when the power member 157 moves in the first direction M, the first power may drive the rotating member and the first transmission portion 153 to rotate in the second direction N, wherein when the power member 157 is rotatable, the first direction M may be the rotation direction of the power member 157, and the second direction N may be the same rotation direction as the first direction M or opposite rotation directions. Taking the second direction N as the same as the first direction M as an example, as shown in fig. 5, when the power member 157 rotates clockwise, the rotating member and the first transmission portion 153 may rotate clockwise, and vice versa, the power member 157, the rotating member and the first transmission portion 153 may also rotate counterclockwise. The relationship between the first direction M and the second direction N is such that the cleaning member 130 and the comb teeth 121 can be relatively displaced in the extending direction of the comb teeth.

According to the dustpan provided by the embodiment of the utility model, the first transmission part 153 is arranged on the rotating member, 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 member 157 drives the rotating member to rotate, the rotating member can convert the rotation of the rotating member into the movement of the second transmission part 155 in the extending direction of the comb teeth, 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 rotating member, the movement stroke of the second transmission part 155 is increased, namely the distance that the comb teeth 121 and the cleaning member 130 slide relatively is increased, so that the cleaning member 130 or the comb teeth 121 can operate for a long enough distance to push filaments such as hairs on the comb teeth 121 into the dustpan 110.

Further, the first power and the second power drive the rotating piece to rotate along the second direction N continuously, so that the switching action between the cleaning process and the resetting process can be continuous, and time and labor are saved.

Further, the first power can drive the rotating member to rotate 180 degrees along the second direction N, and the second power can drive the rotating member to continue to rotate 180 degrees along the second direction N.

As shown in fig. 5, when the first direction M is clockwise, the second direction N may be clockwise. Wherein, through power piece 157 to rotate the piece input first power for the piece can rotate 180 degrees clockwise, likewise, through power piece 157 to rotate the piece input second power, make the piece can rotate 180 back to the origin after clockwise continuation, accomplish the reset.

Further, the first transmission portion 153 is a sliding column, the sliding column deviates from the rotation center 159 of the rotating member, the second transmission portion 155 is a sliding slot, and the sliding column is slidably matched in the sliding slot; under the action of the first power, the rotating piece rotates along the second direction N and can drive the sliding column to rotate along the second direction N and slide in the sliding groove, so that the sliding groove is driven to positively move along the extending direction of the comb teeth; under the action of the second power, the rotating piece rotates along the second direction N and can drive the sliding column to continuously rotate along the second direction N and slide in the sliding groove, so that the sliding groove is driven to reversely move along the extending direction of the comb teeth.

The above-mentioned spool has a rod shape, and one end of the spool is fixed to a position of the rotating member deviated from the rotation center 159, and it is understood that there is a certain 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 second transmission part 155 as an example, the sliding groove may be formed as a long hole, and the length of the long hole may be such that the cleaning member 130 can slide along the extension direction of the comb teeth 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, so that the first distance generated by the first transmission portion 153 in the extending direction of the comb teeth can make the running distance of the cleaning member 130 longer. Of course, the extending direction of the strip hole can also be set at other included angles with the extending direction of the comb teeth.

When the first power acts on the rotating piece, the rotating piece rotates along the second direction N, and the sliding column also rotates along the second direction N, and the sliding column and the sliding groove can slide in a matched manner, so that the sliding column can drive the sliding groove to positively move along the extending direction of the comb teeth. Similarly, when the second power acts on the rotating member, the rotating member rotates along the second direction N, and the sliding column can drive the sliding groove to move reversely along the extending direction of the comb teeth.

Further, the rotating member is a turntable 151, and the sliding column is disposed at an edge of the turntable 151 facing the disk surface of the sliding slot, so that a distance L between the sliding column and a rotation center 159 of the rotating member can approach a radius R of the turntable 151. When the sliding column rotates 180 ° along with the rotation of the turntable 151, the moving distance of the sliding column is close to the diameter of the turntable 151, or the sliding groove is disposed on the cleaning member 130, for example, the moving distance of the cleaning member 130 may also be close to the diameter of the turntable 151, and if the diameter of the turntable 151 is larger, the moving distance of the cleaning member 130 is also larger. Of course, the rotating member may be other than the turntable 151, so long as it can rotate.

Further, the dustpan further comprises a power input wheel 152 and a power output wheel 154 which are in transmission connection, the power element 157 is connected with the power input wheel 152, the power output wheel 154 is connected with the rotating element, and the power element 157 provides at least one group of first power and second power for the power input wheel 152 when moving in the first direction M so as to drive the power output wheel 154 and the rotating element to rotate along the second direction N, wherein the angular speed of the power input wheel 152 is smaller than the angular speed of the power output wheel 154.

The above-mentioned power member 157 outputs the first power and the second power to the power input wheel 152 when moving in the first direction M, so that the power input wheel 152 rotates, the power input wheel 152 transmits the first power and the second power to the power output wheel 154, and the power output wheel 154 acts on the rotating member, so that the rotating member rotates in the second direction N. 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 therefore the power element 157 does not need to move too much distance, and too much movement space is not required to be reserved for the power element 157 on the dustpan 110.

Further, the power input wheel 152 and the power output wheel 154 can be gears, and the gears are directly meshed or indirectly meshed, so that the gear transmission of the power output by the power element 157 is formed, the gear transmission efficiency is high, the structure is compact, the operation is reliable, and the installation space is saved. The power input wheel 152 and the power output wheel 154 may be belt pulleys and connected by belt transmission; the power input wheel 152 and the power output wheel 154 may also be gears and connected by a chain drive.

Further, 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.

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.

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

Further, the angular velocity of the power output wheel 154 is three times that of the transmission gear set, and the angular velocity of the transmission gear set is three times that of the power input wheel 152, so that the power input wheel 152 inputs a smaller angular velocity, and the power output wheel 154 can obtain a larger angular velocity, 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 °, the rotating member 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 distance that the cleaning member 130 moves relative to the comb teeth 121 is the distance between the first position and the second position.

Further, the power member 157 is a rotating pedal, the rotating pedal is connected with an elastic restoring member 160, the rotating pedal can be rotated in the first direction M by stepping on the rotating pedal, at least one group of first power and second power are further output, meanwhile, the rotating pedal can drive the elastic restoring member 160 to elastically deform, the stepping force of stepping on 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 rotating 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. When the treading 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 rotating piece, 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, and objects such as hairs hung on the comb teeth 121 can be scraped again and the cleaning piece 130 is reset.

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 and the rotating member 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 center position of the rotary disc 151, when the sliding column moves down and drives the sliding groove to continue to move right to the right edge of the rotary disc 151, at this time, the cleaning member 130 moves up to the right by 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 anticlockwise, then drive the pinion 156 and the bull gear 158 to rotate 60 degrees again clockwise, then drive the power output wheel 154 and the turntable 151 to rotate 180 degrees again anticlockwise, so that the sliding column moves from the opposite side of the position shown in fig. 3 to the initial position shown in fig. 3, when the sliding column moves from the opposite side of the position shown in fig. 3 to the left and down, the sliding column slides downwards in the sliding groove, and drives the sliding groove to move leftwards to the central position of the turntable 151, when the sliding column moves leftwards and upwards, the sliding groove is driven to continue to move leftwards to the left edge of the disk, namely, the initial position shown in fig. 3, at this time, the cleaning member 130 moves leftwards by the same distance as the sliding groove, so that the reset of the cleaning member 130 is realized.

Further, the power member 157 outputs at least one set of third power and fourth power when moving in the reverse direction M, and the third power can drive the cleaning member 130 and the comb teeth 121 to slide relatively in the forward direction in the extending direction of the comb teeth, so that the cleaning member 130 cleans the comb teeth 121; the fourth power can drive the cleaning member 130 and the comb teeth 121 to relatively slide in the opposite direction in the extending direction of the comb teeth, so that the cleaning member 130 and the comb teeth 121 are reset.

It will be appreciated that the power member 157 may be moved in either the first direction M or the reverse direction of the first direction M, and that the power output by the power member 157 in the reverse direction of the first direction M may be the third power and the fourth power for the convenience of distinction. When the power element 157 moves reversely, the third power and the fourth power are output to the rotating element, the third power can drive the first transmission part 153 to rotate reversely around the rotation center 159 of the rotating element, and further drive the second transmission part 155 to move forward in the extending direction of the comb teeth, and further drive the cleaning element 130 and the comb teeth 121 to slide relatively forward in the extending direction of the comb teeth, so that the cleaning element 130 cleans the comb teeth 121; the fourth power can drive the first transmission part 153 to reversely rotate around the rotation center 159 of the rotating member, further drive the second transmission part 155 to reversely move in the extending direction of the comb teeth, and further drive the cleaning member 130 and the comb teeth 121 to reversely and relatively slide in the extending direction of the comb teeth, 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 rotating member can be realized, and the reset of the relative movement of the cleaning member 130 and the comb teeth 121 is realized. The forward rotation, the reverse rotation and the forward rotation and reverse rotation of the rotating member are all freely operated by the user, and the reverse rotation is not necessarily driven by the elastic reset member 160, and can be driven by the user independently.

In one embodiment, the power element 157 is a rotating pedal, and when the rotating pedal is stepped on, the rotating pedal outputs the first power and the second power, and the limiting element 170 is arranged on the dustpan 110 to limit the rotating angle of the rotating pedal.

With continued reference to fig. 2, when the rotating pedal is depressed, the rotating pedal rotates, so that the first power and the second power can be output, and when the rotating pedal abuts against the lower limiting member 170, the rotating pedal does not rotate downward any more.

In other embodiments, the power member 157 may be a knob, and the knob may be used instead of the rotating pedal. Alternatively, the power member 157 may be a button, where a rack is disposed on the inner side of the button and engaged with the power input wheel 152, and when the button is pressed, the button may drive the rack to move, and the rack may move to drive the power input wheel 152 to rotate.

Continuing to combine with the illustration of fig. 3, the dustpan further comprises a mounting box 140, wherein the mounting box 140 is arranged in the dustpan bucket 110, the cleaning member 130 is slidably supported on the mounting box 140, wherein the driving mechanism 150 is arranged in the mounting box 140, and the rotating member can be rotatably connected with the mounting box 140. The mounting box 140 includes a left box 141, a right box 145 and a base 143, and the stopper 170 may be mounted on the right box 145, and one end of the elastic restoring member 160 is connected with the mounting box 140.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
