[0037] Combine the following Figures 1 to 8 , describing an embodiment of the utility model. The utility model provides a dustpan 1, which may include a dustpan body 10, a cleaning part 20 and a driving mechanism. The dustpan body 10 is provided with a comb tooth part 110 for combing bristles. The cleaning part 20 is provided on the dustpan body 10, and is configured to slide back and forth between a first position and a second position along the extension direction of the comb tooth part 110 to clean the debris on the comb tooth part 110. The driving mechanism may include a cam transmission part 310 and a push-range driving part 320, the cam transmission part 310 is rotatably provided on the dustpan body 10, the push-range driving part 320 is connected to the cam transmission part 310 to drive the cam transmission part 310 to rotate, and the cam transmission part 310 rotates to drive the cleaning part 20 to slide from the first position to the second position.
[0038] In some embodiments, the dustpan body 10 has a forwardly open accommodation space 120 for storing garbage. The top wall 132 of the dustpan body 10 can be arranged further back than the bottom wall 134, and the comb teeth 110 can be arranged at the front end of the top wall 132, so that it is convenient for the user to comb the bristles of the broom on the comb teeth 110, and secondly, it is convenient for the hair falling on the comb teeth 110 to be received by the bottom wall 134, so as to prevent the hair from falling to the outside of the dustpan body 10.
[0039] The cleaning portion 20 can slide back and forth between the first position and the second position along the extending direction of the comb-tooth portion 110 . During the sliding process, the cleaning portion 20 can scrape off the hair wound around the comb-tooth portion 110 .
[0040] In this embodiment, the driving mechanism is used to drive the cleaning part 20 to slide between the first position and the second position, wherein in the driving mechanism, the push drive part 320 and the cam transmission part 310 can drive the cleaning part 20 to slide from the first position to the second position, without the need for the user to clean by hand, which is simple and convenient.
[0041] In some specific embodiments, the cam transmission part 310 can be set as a disc cam, that is, the cam transmission part 310 is a disc-shaped component that rotates around a fixed axis and has a variable diameter. The cam transmission part 310 can be set at a side of the first position away from the second position. When the cam transmission part 310 rotates, the cleaning part 20 can be pushed to slide from the first position to the second position by using its profile to achieve combing and shaving hair.
[0042] Furthermore, the push-stroke driving part 320 is used to drive the cam transmission part 310 to rotate, and its form can be set in various forms.
[0043] In some specific embodiments, the push-range driving part 320 can be configured to directly provide rotational torque to the cam transmission part 310. For example, the push-range driving part 320 can be a driving motor drivingly connected to the cam transmission part 310, or even a handle for receiving external force applied by the user.
[0044] In some other specific embodiments, the push-stroke driving part 320 can also indirectly provide a rotational torque through a transmission mechanism that converts linear motion into circular motion. For example, the push-stroke driving part 320 can be configured to be driven to move along a straight line, and by converting it into a rotational torque, the cam transmission part 310 is driven to rotate. The transmission mechanism that converts linear motion into circular motion can be of various types, such as a rack and pinion mechanism, a slider mechanism, etc.
[0045] In some embodiments, the cam transmission part 310 is configured to rotate around the center of its base circle O, and the cam transmission part 310 has a convex part 312 protruding from the base circle O. When the convex part 312 rotates in a direction close to the cleaning part 20, the cleaning part 20 is pushed to slide from the first position to the second position. When the convex part 312 rotates in a direction away from the cleaning part 20, the cleaning part 20 slides from the second position to the first position.
[0046] The base circle O refers to a circle in the cam transmission part 310 with the minimum radial diameter of the profile as the radius, and the cam transmission part 310 rotates around the center of the base circle O. When the cam transmission part 310 rotates, when the convex part 312 protruding from the base circle O rotates in the direction close to the cleaning part 20, it is the push stroke, pushing the cleaning part 20 to slide from the first position to the second position. When the convex part 312 rotates in the direction away from the cleaning part 20, it is the return stroke, so that the cam transmission part 310 can gradually release the space between the second positions, and the driving mechanism drives the cleaning part 20 to slide from the second position to the first position. In this way, the reciprocating motion of the cleaning part 20 is achieved.
[0047] Further, the cam transmission part 310 can also be configured as a symmetrical cam, and the cam transmission part 310 has a base 314 located on the base circle O. The base 314 has a first near rest point and a second near rest point symmetrically distributed along its symmetry axis, and the convex part 312 has a far rest point. When the first near rest point contacts the cleaning part 20, the cleaning part 20 is in the first position. When the far rest point contacts the cleaning part 20, the cleaning part 20 is in the second position. When the second near rest point contacts the cleaning part 20, the cleaning part 20 is in the first position.
[0048] Symmetrical cam means that the protrusions 312 on the cam transmission part 310 are symmetrically distributed about the cam centerline. The far rest point is the point farthest from the rotating axis during the movement of the cam transmission part 310. Since the cam transmission part 310 is a symmetrical cam, the far rest point is the point on the protrusion 312 and on the symmetry axis.
[0049] The near-rest point refers to the point closest to the rotating shaft during the movement of the cam transmission part 310. Since the cam transmission part 310 has a base 314 located on the base circle O, the first near-rest point and the second near-rest point are located on the base circle O and are symmetrically distributed along its symmetry axis. Since the cam transmission part 310 drives the cleaning part 20 to move between the first position and the second position continuously, the first near-rest point is located at the intersection of the base 314 and the convex part 312 on one side, and the second near-rest point is located at the intersection of the base 314 and the convex part 312 on the other side.
[0050] In some embodiments, a gear structure 316 is provided on the cam transmission part 310. A rack structure 322 is provided on the push-range driving part 320, and the rack structure 322 is meshed with the gear structure 316. The push-range driving part 320 is also configured to be operably moved to drive the rack structure 322 to move, thereby driving the gear structure 316 to drive the cam transmission part 310 to rotate.
[0051] That is to say, in this embodiment, the push-stroke driving part 320 is driven to move in a straight line, and the push-stroke driving part 320 and the cam transmission part 310 are connected through the rack structure 322 and the gear structure 316, so that the linear driving force of the push-stroke driving part 320 is converted into the torque of the cam transmission part 310, thereby driving the cleaning part 20 to move from the first position to the second position.
[0052] In some further embodiments, since the cam transmission portion 310 has a base 314 on the base circle O, and the base 314 does not play a role in pushing the cleaning portion 20, that is, when the cam transmission portion 310 rotates, the contour of the base 314 is always on the base circle O, the gear tooth structure 316 can be set on the base 314.
[0053] In some embodiments, the push-range driving unit 320 can also be configured to drive the rack structure 322 to move by moving up and down, and the push-range driving unit 320 has an upward position, a middle position and a downward position arranged in sequence from top to bottom.
[0054] When the push-stroke driving portion 320 moves from the lifting position to the middle position, the cam transmission portion 310 is driven to rotate around the working direction and the convex portion 312 is caused to rotate toward the cleaning portion 20 .
[0055] When the push-stroke driving portion 320 moves from the middle position to the downward pressing position, the cam transmission portion 310 is driven to rotate around the working direction and the convex portion 312 is rotated in a direction away from the cleaning portion 20 .
[0056] That is, when the push-stroke driving part 320 moves from top to bottom once, the push-stroke driving part 320 can drive the cam transmission part 310 to make a push-stroke motion and a return motion, thereby enabling the cleaning part 20 to make a reciprocating motion between the first position and the second position. That is, when the push-stroke driving part 320 moves from top to bottom once, the cleaning part 20 can reciprocate the comb teeth part 110, thereby improving the cleaning efficiency of the cleaning part 20 and enhancing the user experience.
[0057] In some special embodiments, the push-stroke driving part 320 can also be configured such that when it is in the lifting position, the cleaning part 20 is in the first position when the first near rest point contacts the cleaning part 20. When it is in the middle position, the cleaning part 20 is in the second position when the far rest point contacts the cleaning part 20. When it is in the pressing position, the cleaning part 20 returns to the first position when the second near rest point contacts the cleaning part 20.
[0058] Furthermore, the dustpan 1 may further include a restoring member 40 , which is disposed on the dustpan bucket body 10 and connected to the push-range driving portion 320 , and is configured to provide an upward restoring force to the push-range driving portion 320 .
[0059] The reset member 40 may be a compression spring. When the push-range driving part 320 is driven to move from the upward position to the downward position under the action of an external force, the reset member 40 is gradually compressed to generate an upward restoring force. When the external force is removed, the push-range driving part 320 may return from the downward position to the upward position under the action of the restoring force.
[0060] In the process of the push-range driving part 320 returning from the pressing position to the middle position, the push-range driving part 320 can drive the cam transmission part 310 to rotate in the direction opposite to the working direction, and make the convex part 312 rotate toward the cleaning part 20. When the push-range driving part 320 moves from the middle position to the lifting position, the cam transmission part 310 is driven to continue to rotate in this direction, and make the convex part 312 rotate in the direction away from the cleaning part 20. That is to say, in the process of the push-range driving part 320 returning from the pressing position to the lifting position by the reset member 40, a push-range motion and a return motion are completed in the opposite direction, and the cleaning part 20 is again realized to comb the combing part by reciprocating.
[0061] That is to say, when the user applies a force from the lifting position to the pressing position to the push-stroke driving part 320 , the cleaning part 20 is reciprocated and slid twice between the first position and the second position, which greatly improves the combing efficiency of the cleaning part 20 .
[0062] In some embodiments, the dustpan 1 may further include an operating rod 50 for moving the dustpan bucket 10 .
[0063] In some specific embodiments, the operating rod 50 may also be configured to be operable to move up and down so as to directly serve as the push-stroke driving unit 320 .
[0064] In some other specific embodiments, the operating rod 50 and the push-range driving part 320 may be two separate components. The operating rod 50 extends in the up-down direction and is connected to the push-range driving part 320. The operating rod 50 may also be configured to be operable to move up and down to drive the push-range driving part 320 to move up and down.
[0065] In some embodiments, the dustpan 1 may further include a positioning post 60 , which is fixed to the dustpan bucket 10 and extends up and down. The push-range driving part 320 is telescopically connected to the positioning post 60 , so that the positioning post 60 is used to constrain the moving track of the push-range driving part 320 .
[0066] Furthermore, the push-range driving part 320 is configured as a hollow rod sleeved on the outside of the positioning column 60 so that the push-range driving part 320 and the positioning column 60 are telescopically connected.
[0067] In some embodiments, the driving mechanism may further include a return driving unit 330 , which is disposed on the dustpan body 10 and connected to the cleaning unit 20 , and is configured to drive the cleaning unit 20 to slide from the second position to the first position.
[0068] As can be seen from the above, in the driving mechanism, when the convex portion 312 rotates toward the cleaning portion 20, it can drive the cleaning portion 20 to slide from the first position to the second position (i.e., the push stroke). When the convex portion 312 rotates in the direction away from the cleaning portion 20 (i.e., the return stroke), the cam transmission portion 310 can gradually release the space between the first position and the second position. At this time, the cleaning portion 20 can be driven by the driving mechanism to slide from the second position to the first position under the action of the return stroke driving portion 330.
[0069] In some specific embodiments, the return drive unit 330 is an elastic member. When the cleaning unit 20 slides from the first position to the second position, the elastic member is stretched and generates an elastic restoring force, and when the protrusion 312 rotates away from the cleaning unit 20, the elastic restoring force is used to cause the cleaning unit 20 to slide from the second position to the first position.
[0070] Furthermore, the number of elastic members may be multiple (eg, two, three or more), and the multiple elastic members are further configured to generate a combined elastic restoring force at the center of the cleaning portion 20 to allow the cleaning portion 20 to slide more smoothly.
[0071] In some other specific embodiments, the return drive unit 330 may also be in other forms, such as a drive motor, etc., as long as it can apply a force to the cleaning unit 20 to slide from the second position to the first position.
[0072] In some embodiments, the dustpan body 10 has a accommodating space 120 open forward, and the comb tooth portion 110 may include a plurality of comb teeth 112, each comb tooth 112 is formed at the front end of the top wall 132 of the dustpan body 10 extending along the front-to-back direction, and the plurality of comb teeth 112 are arranged at intervals along the width direction of the dustpan body 10.
[0073] The cleaning part 20 may also include a main plate 210 and a combing plate 220. The main plate 210 is arranged on the top wall 132 of the dustpan body 10, and the combing plate 220 is arranged at the front end of the main plate 210. The combing plate 220 has a plurality of combing holes 222 that match the comb teeth 112 one by one. When the cleaning part 20 slides in the front and rear directions, the combing holes 222 are used to comb and scrape out impurities.
[0074] Further, when the cleaning part 20 is in the first position, the combing plate 220 is located at the rear end of the comb teeth 112. When the cleaning part 20 is in the second position, the combing plate 220 is located at the front end of the comb teeth 112.
[0075] Since the cam transmission part 310 is disposed at the side of the first position away from the second position, the cleaning part 20 is pushed from the first position to the second position. When the cleaning part 20 is in the first position, the combing plate 220 is at the rear end of the comb teeth 112, and when the cleaning part 20 is in the second position, the combing plate 220 is at the front end of the comb teeth 112, so the cam transmission part 310 is disposed at the rear end of the cleaning part 20.
[0076] Furthermore, the cleaning portion 20 may further include an abutment rod 230 , which is connected to the rear of the main body plate 210 and contacts the cam transmission portion 310 so that the cam transmission portion 310 acts on the cleaning portion 20 .
[0077] Specifically, the cam transmission part 310 can be arranged to be connected to the dustpan bucket body 10 for forward and backward rotation, and the abutment rod 230 can be extended in the up and down directions and arranged behind the main plate 210, so as to increase the contact area between the cleaning part 20 and the cam transmission part 310 to ensure that the cam transmission part 310 can push the cleaning part 20.
[0078] Furthermore, the dustpan body 10 is further provided with an installation space 140 in the accommodation space 120. The cam transmission part 310 is at least partially located in the installation space 140 and is connected to the side wall of the installation space 140 through the rotating shaft 318, so that the cam transmission part 310 can be isolated from the accommodation space 120, creating a clean working environment for the cam transmission part 310.
[0079] In addition, since the cam transmission part 310 is at least partially located in the installation space 140, in order to facilitate the abutment rod 230 to be in good contact with the cam transmission part 310, the abutment rod 230 can also be set in the installation space 140. This not only can accommodate the abutment rod 230 and make the overall structure more compact, but also can utilize the limiting relationship between the abutment rod 230 and the front wall 142 of the installation space 140 to limit the displacement of the cleaning part 20, thereby preventing the cleaning part 20 from escaping from the comb tooth part 110.
